Sami Sakari Salo (born 2 September 1974) is a Finnish former professional ice hockey player who was a defenceman in the National Hockey League (NHL). He began his professional career with TPS of the SM-liiga before being selected by the Ottawa Senators with their last pick in the 1996 NHL entry draft.

He joined the Senators in 1998–99 and was selected to the NHL All-Rookie Team. In the 2002 off-season, he was traded to the Vancouver Canucks with whom he recorded three 30-point campaigns. Prior to the 2012–13 NHL season he signed with the Lightning as a free agent. Due to the 2004–05 NHL lockout, Salo played overseas with Frölunda HC of the Swedish Elite League and helped the club capture the Le Mat Trophy as league champions. Internationally, Salo has competed for Finland, appearing in two World Championships, three Winter Olympics and one World Cup. He won silver medals at the 2001 World Championships and the 2006 Winter Olympics, as well as a bronze medal at the 2010 Winter Olympics.

Throughout his career, Salo became infamous for being injury-prone, having suffered over 40 career injuries. Despite his injuries, he was known as a two-way defenceman with a powerful slapshot.

After developing his skills with the junior club of his hometown, Turku, Finland, Salo turned professional with TPS of the SM-Liiga in 1994–95. He appeared in seven games, recording a goal and two assists in his first season in the SM-Liiga. The following campaign, he recorded a Finnish career-high 14 assists and 21 points over 47 games. In the off-season, Salo was selected by the Ottawa Senators with their last selection in the 1996 NHL entry draft, 239th overall in the ninth round. He remained in Finland for two more seasons upon being drafted. He improved from seven goals to nine in 1996–97. The following season, he transferred from TPS to Jokerit. In his lone season with the Helsinki-based team, he tallied three goals and eight points over 35 games.

Following a four-year career in Finland, Salo signed with the Senators in July 1998. He played in the first 3 games of the 1998/99 season before he was assigned to the Detroit Vipers, Ottawa's International Hockey League (IHL) affiliate, due to his first NHL injury and was recalled on 18 November 1998. Twenty-seven games into his rookie campaign, he scored his first NHL goal against Boston Bruins goaltender Byron Dafoe, a game-winner, in a 3–1 win on 21 January 1999. Completing the 1998–99 season with seven goals and 19 points, he was named to the NHL All-Rookie Team. The following season, Salo notched a hat trick in a 6–4 win against the Pittsburgh Penguins on 30 March 1999. His campaign was shortened, however, to 37 games due to injury and he was limited to 14 points. In 2000, he missed two games as he suffered from a snakebite.

Salo continued to be sidelined in 2000–01 with various ailments, including shoulder, foot and knee injuries, as well as the flu. In March 2001, he was also cross-checked in the face by Rick Tocchet of the Philadelphia Flyers, suffering broken teeth and a mild concussion. He finished his third NHL season with 18 points in 31 games.

Before the 2001–02 season began, Salo injured his groin in an exhibition game against the Toronto Maple Leafs in September. In addition to missing the first three games of the season, he was later sidelined for a total of 13 more contests due to separate cases of the flu, a broken finger and back spasms. He recorded 18 points in 66 games. In the proceeding off-season, Salo underwent shoulder surgery. Becoming a free agent, he accepted an $880,000 qualifying offer from the Senators on 31 July 2002. Nearly two months later, he was traded to the Vancouver Canucks in exchange for forward Peter Schaefer on 21 September.

Salo established himself as a top-four defenceman with the Canucks, ranking fourth among team blueliners in average ice time per game during his first season with Vancouver. He also appeared in a career-high 79 games while recording nine goals, 21 assists and 30 points.
