Seth Martin (May 4, 1933 – September 6, 2014) was a Canadian ice hockey player. He played professionally for the St. Louis Blues of the National Hockey League. He was inducted into the International Ice Hockey Federation Hall of Fame in 1997.

Seth Martin helped the Trail Smoke Eaters win the 1961 World Ice Hockey Championships as the last amateur team to win the World Championships from Canada. He was named the best goaltender of the tournament. He also played in four more World Championships with the Trail Smoke Eaters where he was named best goaltender in three of the four tournaments. In 1964, he played with team Canada at the Olympics where the team finished fourth. Martin played for the St. Louis Blues in 1967–1968, appearing in 30 games as backup for Glenn Hall. The Blues made it to the Stanley Cup Finals but lost in four straight to the Montreal Canadiens.

After the season Martin had to choose between continuing his NHL career and keeping his firefighters pension. He chose the latter and moved back to Trail, British Columbia but continued to play hockey and eventually coach. He died after a heart attack in 2014 in Trail, British Columbia, aged 81.
