Andrew Cogliano (born June 14, 1987) is a Canadian former professional ice hockey player who played for the Edmonton Oilers, Anaheim Ducks, Dallas Stars, San Jose Sharks, and Colorado Avalanche of the National Hockey League (NHL). On December 31, 2013, Cogliano became the 20th player in NHL history to play 500 consecutive games, and only the fifth to do so from the beginning of his NHL career. On November 4, 2017, Cogliano played in his 800th consecutive game, placing him in fourth place on the NHL's most consecutive games played list. The streak ended at 830 games on January 14, 2018, when Cogliano was suspended for two games. Cogliano won the Stanley Cup with the Avalanche in 2022.

Cogliano was born on June 14, 1987, in Toronto, Ontario, to parents Carm and Theresa. His father worked for the Toronto Parks, Forestry and Recreation Division while his mother worked as a fitness instructor and a preschool teacher. He began skating at the age of four after watching his older brother Matthew but also played soccer until he was 15 years old. Growing up, Cogliano attended St. Michael's College School from Grade 7 to Grade 13.

Cogliano started playing select ice hockey for the Richmond Hill Vaughan Kings in the North York Hockey League. As a member of the Vaughan Kings AA team, Cogliano played in the 2001 Quebec International Pee-Wee Hockey Tournament. He then advanced to the Vaughan Kings AAA team for the 2002–03 season, where he recorded 21 goals and 34 assists through 34 games. Although he was a high ranked prospect heading into the 2003 Ontario Hockey League (OHL) Priority Selection draft, Cogliano informed teams he was considering playing college hockey instead of major junior. He was eventually drafted in the third round, 54th overall, by the Toronto St. Michael's Majors.

As a St. Michael's College School student, Cogliano played for their U14 team and the Double Blues before finishing with the St. Michael's Buzzers in the Ontario Junior Hockey League (OJHL). As a member of the Double Blues, Cogliano surpassed Jason Spezza's points-per-game program record en route to the 2003 Goetz Classic Cup. After scoring a goal and two assists in the championship game, Cogliano was named the game's MVP. In his first season with the Buzzers, Cogliano finished second on the team with 26 goals and 46 assists for 72 points. After adding 11 goals and 21 assists in the playoffs, he was also named the 2004 OPJHL-South Rookie of the Year and one of the OHA's Top Prospects. Cogliano finished his career with the Buzzers as the program's leader in assists, points, three-goal games, and four-goal games. While he was originally ranked 63rd by the NHL Central Scouting Bureau, changes to the NHL's rulebook post lockout raised his stocks among scouts. As such, he was drafted in the first round, 25th overall, by the Edmonton Oilers in the 2005 NHL entry draft.

Following the 2005 draft, Cogliano enrolled in the University of Michigan's School of Kinesiology and joined the Michigan Wolverines men's ice hockey team for two seasons. While the Wolverines started the 2005–06 season with a 4–0–0 record, Cogliano's first collegiate point came in his fourth game of the season. As he was struggling to score, Cogliano was gifted an Easton Synergy stick, the same one he used in juniors, before his fourth game of the season. In that game, on October 16, he scored his first collegiate power-play and game-winning goal against the Merrimack Warriors. Through the first 17 games of the season, Cogliano played on the Wolverine's third line with fellow freshmen Travis Turnbull and Tim Miller. Over two games in the first week of November, Cogliano recorded three goals and three assists to maintain his six-game scoring streak. He was subsequently recognised by the Central Collegiate Hockey Association (CCHA) as the conference's Rookie of the Week on November 7. He ranked third on the team in scoring with 19 points through his first 17 games but struggled after returning from the 2006 World Junior Ice Hockey Championships. Cogliano finished the season with 28 points in 39 games and was named to the 2005–06 CCHA All-Rookie team.

Cogliano improved on his freshman scoring total upon returning to the Wolverines for the 2006–07 season. He began December with his first NCAA hat-trick to maintain his team lead in scoring with 12 goals. However, he then missed numerous games in December due to a shoulder injury and the 2007 World Junior Ice Hockey Championships. Unlike the previous season, Cogliano had time to recover after the World Juniors and quickly returned to his scoring prowess. In his first seven games back with the Wolverines, Cogliano tallied five goals and extended his scoring streak to a career-best 12 games. Cogliano finished his sophomore season tied for seventh in the conference with 24 goals and eighth with 50 points. On May 2, 2007, he officially concluded his collegiate career by signing a professional contract with the Edmonton Oilers.

Leading up to the 2007–08 season, Cogliano had a strong training camp and made the Oilers' opening night roster. He made an immediate impact in his NHL debut on October 4, 2007, by tallying his first NHL assist in the Oilers' 3–2 win over the San Jose Sharks. He added another assist in his second game before scoring his first NHL goal on October 8, 2007, against the Detroit Red Wings. By October 15, Cogliano led the Oilers in scoring with five points. However, his scoring rate began to decline as the season continued and he adjusted to the NHL's 82-game schedule. Before the league's three-day Christmas break, Cogliano ranked fourth on the Oilers with six goals and 10 assists and seventh among all NHL rookies. In mid-January, Cogliano began centering the Oilers' "Kid line" with Sam Gagner and Robert Nilsson to boost scoring among the trio. They were referred to as the "Kid line" as all three were under the age of 24. By the start of March, Cogliano had scored 13 goals and was tied with Gagner for fourth on the team with 35 points. On March 11, 2008, Cogliano set an NHL record by scoring overtime goals in three consecutive games. His stick and gloves were subsequently sent to the Hockey Hall of Fame. Over the final 20 game of the season, Cogliano recorded nine goals and eights assists as the Oilers maintained a 14-5-1 record. The "Kid line" was largely credited for the Oilers' playoff push in the second half of the season, although they would ultimately fall short of qualifying for the 2008 Stanley Cup playoffs. He finished his rookie season with 18 goals and 27 assists and was ninth in Calder Memorial Trophy voting for the NHL's Rookie of the Year.

While the "Kid line" was reunited to start the 2008-09 season, they were occasionally split up over October and November due to scoring lapses. Oilers coach Craig MacTavish was critical of the line's lack of success and said he was "not totally convinced" on their usefulness. He eventually split up the line and moved Cogliano into a winger position with Shawn Horcoff and Dustin Penner. After returning from the holiday break, Cogliano scored four goals over seven games to tie Sheldon Souray for the team lead with 12. As such, he was invited to represent the Sophomore team in the NHL YoungStars Game at the 2009 National Hockey League All-Star Game. He also participated won the "Fastest Skater" competition during the SuperSkills event, clocking in at a time of 14.31 seconds. However, before and after returning from the All-Star Game, Coglaino experienced a 16-game scoring drought that was snapped in mid-February. By March, Cogliano had tallied 16 goals and 34 points while averaging 14:57 minutes per game. He added two goals by the end the season to match his rookie-season total of 18 goals but failed to match his previous season's point total. In June 2009, Cogliano was confirmed to be a part of a planned trade that would include Ladislav Šmíd and Dustin Penner being sent to the Ottawa Senators in exchange for Dany Heatley. However, Heatley ultimately exercised the no-trade clause in his contract and the deal did not materialize.
