Brandon Gormley (born February 18, 1992) is a Canadian professional ice hockey defenceman who is currently an unrestricted free agent. He most recently played for the Iserlohn Roosters of the Deutsche Eishockey Liga (DEL). He was selected 13th overall by the Phoenix Coyotes in the 2010 NHL Entry Draft. During his junior career, he was named to the QMJHL All-Rookie Team, is a two-time QMJHL Second Team All-Star and won the President's Cup with the Wildcats in 2010. Internationally, he has competed in two World U-17 Hockey Challenges, one Ivan Hlinka Memorial Tournament and one IIHF World U20 Championship.

Gormley left his home in Prince Edward Island at the age of 14 to compete with the Athol Murray College of Notre Dame's hockey program in Wilcox, Saskatchewan. He played two years of midget hockey with the Notre Dame Hounds in the Saskatchewan Midget AAA Hockey League. In 2007–08, he scored 23 goals, and 53 points over 42 games as a 16-year-old, after which the Moncton Wildcats made him the first overall selection in the 2008 Quebec Major Junior Hockey League (QMJHL) Draft. He joined the Wildcats in 2008–09 and scored 7 goals and 27 points for Moncton in 62 games. His efforts earned him QMJHL All-Rookie Team honours.

He improved to 9 goals and 43 points for the Wildcats in 2009–10 and added 17 more points in the playoffs, the third-highest post-season total among league defencemen. Gormley and the Wildcats won the President's Cup as QMJHL champions, earning a berth in the 2010 Memorial Cup. He scored three points in three games in the national tournament, but the Wildcats lost all three games and were eliminated. Individually, he was voted the recipient of the Mike Bossy Trophy in 2010 as the Quebec League's top professional prospect. He was also named a Second-Team QMJHL All-Star.

Gormley finished the season highly rated for the 2010 NHL Entry Draft. The NHL Central Scouting Bureau listed him sixth among North American skaters, while the International Scouting Services listed him third among all skaters. Scouts described Gormley as "well rounded, but not dynamic" and praised his intelligence on the ice and ability to move the puck. Gormley went on to be selected 13th overall by the Phoenix Coyotes.

He attended his first NHL training camp in September 2010 before being returned to the Wildcats. Playing in his third QMJHL season, Gormley recorded 13 goals and 48 points over 47 games; he was named to the QMJHL Second All-Star Team for the second consecutive year. He added an assist over five post-season games as the Wildcats were eliminated in the first round of the QMJHL playoffs, failing to defend their league title. With his junior season over, the Coyotes assigned him to their American Hockey League (AHL) affiliate, the San Antonio Rampage. He played in four AHL games, recording an assist.

In his fourth season with the Wildcats, Gormley played 26 games before being traded to complete his junior career with the Shawinigan Cataractes hours before the January 7, 2012, QMJHL trade deadline.

Gormley was assigned to the Coyotes' new AHL affiliate, the Portland Pirates, to begin his first full professional season in 2012–13 season. He appeared in 68 games with the Pirates and ranked second among the blueline with 24 assists and 29 points.

In the second year of his entry-level contract, Gormley remained with the Pirates, quickly assuming leadership responsibilities to be selected as an Alternate Captain for the 2013–14 season. Gormley was used heavily in all situations with the Pirates and was placing 8th in the AHL in scoring amongst blueliners, before he received his first NHL recall by Phoenix on March 7, 2014. He made his NHL debut on March 10, 2014, against the Tampa Bay Lightning. Gormley featured in 5 games with the Coyotes going scoreless before he was returned to Portland to finish the season with new career offensive highs all across the board.
