Johannes Kotkas (3 February 1915 – 8 May 1998) was a heavyweight Greco-Roman wrestler from Estonia who won a gold medal at the 1952 Summer Olympics.

He soon became the second-best Estonian heavyweight wrestler, consistently losing to Kristjan Palusalu in the finals of national championships.

Palusalu retired around 1938 due to an injury, opening for Kotkas the way to the Estonian and European titles.

In 1943–1950 he also competed nationally in freestyle wrestling, sambo, hammer throw, shot put and weightlifting and placed within the podium at least once in each of those disciplines.
