Ivan Ernst Baumgartner (11 March 1934 – 30 December 2020) was an Australian rules footballer who played with Geelong, Melbourne and St Kilda in the Victorian Football League (VFL). After studying at Wesley College, Baumgartner moved to Geelong, in order to attend the Gordon Institute of Technology. While there he played with the Geelong Football Club. In 1953, his first season, he appeared in Geelong's preliminary final win over Footscray. He lost his place in the side for the grand final, to make way for Russell Renfrey, and had to watch his club's defeat of Collingwood from beyond the sidelines. The following year he was a regular member of the team and played a total of 17 games, including two more finals, but not a grand final.
