Frederick Joseph "Bun" Cook (September 18, 1903 – March 19, 1988) was a Canadian professional ice hockey forward and coach.

Cook was a member of two Stanley Cup championship teams with the Rangers, in 1928 and 1933, playing on the "Bread Line" with his brother Bill and Frank Boucher.

Cook turned to coaching in 1937 and spent 19 years in the American Hockey League (AHL), with the Providence Reds for six seasons and the remainder with the Cleveland Barons.

Cook was named an AHL All-Star coach on six occasions, and led his teams to a record seven Calder Cup championships.

[3] Despite their eight-year difference age, Bun frequently followed Bill to new teams and the pair spent most of their careers playing together.

[3] Following the championship, Bun turned professional by signing with the Saskatoon Crescents of the Western Canada Hockey League (WCHL) for the 1924–25 season.

[1] Bill had already played two years in Saskatoon by that point and housed his younger brother during their shared tenure with the team.

The Montreal Maroons intended to sign both Cook and his brother Bill to join their team for the 1926–27 NHL season.

[7] The Rangers finished second in the American Division that season and defeated the Pittsburgh Pirates and Boston Bruins to reach the 1928 Stanley Cup Finals against the Maroons.

[1] The second game was notable for having Rangers coach Lester Patrick play goal after regular goaltender Lorne Chabot was injured.

[5] Attempting to defend their championship, the Rangers reached the 1929 Stanley Cup Finals, but were defeated by the Boston Bruins.

[5] The Rangers won the American Division title and reached the 1932 Stanley Cup Finals but lost the series to the Toronto Maple Leafs.

Bill ultimately scored the winning goal in a 1–0 victory as the Rangers won their second Stanley Cup championship.

[4] Often overshadowed by his linemates, he was the last member of the Bread Line to gain entry into the Hall, as he followed Bill (1952) and Frank Boucher (1958).

[14] Occasionally pressed into playing duty, Cook also appeared in 37 games for the Reds over that time, and recorded what ultimately was his final professional goal, the game-winner in a 3–2 victory over the New Haven Eagles on December 17, 1942.

Though the team reached the league championship series, the Barons opted to relieve Cook of his position as coach.
