Clifford Joseph "Fido" Purpur (September 26, 1914 – February 21, 2001) was an American ice hockey player who played five seasons in the National Hockey League for the St. Louis Eagles, Chicago Black Hawks, and Detroit Red Wings between 1934 and 1945.

In 1941 Purpur left St. Louis and joined the Kansas City Americans but received a brief call-up for his second stint in the NHL for the Chicago Black Hawks.

Due to America's entry into World War II several NHL rosters were depleted of talent and the league scrambled to find replacements.

Purpur split his time in 1944-45 between Chicago and Indianapolis of the newly-formed AHL but after the Capitals bowed out in the first round of the playoffs Purpur made his final appearance in the NHL by appearing in seven playoff games for the Detroit Red Wings.

Purpur would spend seven seasons with the Fighting Sioux and shepherded the team through the early years of conference play.
