Mahmoud Guendouz (born 24 February 1953 in El Harrach) is an Algerian former footballer and coach.

A stalwart of the Algerian national team, he appeared at the 1980 Olympics as well as the FIFA World Cups of 1982 and 1986.

As a club player he was largely based in his homeland, although he also appeared for FC Martigues in France.

[citation needed] Guendouz played every minute of Algeria's World Cup finals campaign of 1982 and was solid in a campaign in which les Fennecs won two games out of three and only missed out on the second round due to goal difference.

He did blot his copy book, however, with a foul on Patricio Yáñez in the game against Chile, with Miguel Ángel Neira scoring from the resulting penalty.
