Alastair Brennan (born 17 February 1945) is a retired ice hockey player who played in Scotland and for the Great Britain national ice hockey team. He is a member of the British Ice Hockey Hall of Fame.
Alastair Brennan first played senior hockey in the early sixties for the Paisley Mohawks. Brennan's older brother, Billy Brennan was the club's player-coach. In 1970, the Mohawks folded and Brennan went to play for the Ayr Bruins. In 1972, Brennan was involved in a car accident and suffered from a broken neck. He was told that we would not be able to play ice hockey again. Although Brennan fought his way to a full recovery he found that no coach was prepared to play him for fear of causing further injury. However, Lawrie Lovell, Fife Flyers' player-coach eventually gave Brennan a chance and he went on to play seven seasons with the club.
Brennan returned to the Bruins as player-coach in 1979. Brennan played briefly for the Dundee Rockets during the 1982–83 season where he helped the team win the league championship before returning again to the Bruins as player-coach. Brennan then stayed with the Bruins until he retired from ice hockey in 1984 following the playoffs at Wembley Arena. Brennan remained with the Bruins as an assistant coach the following season, 1984–85, even icing for the team one last time in 1985.
Brennan first appeared for the Great Britain national ice hockey team in 1965. He went on to appear for his country 102 times, competing in eight World Championships against 22 other nations.
