Teemu Rannikko (born September 9, 1980) is a Finnish former professional basketball player and currently working as an assistant coach of Finland national team.

He had his most successful seasons over the next two years in Union Olimpija, where he was one of the key players for the team that played in the EuroLeague.

In 2007–08, he moved to BC Khimki, where he played his first season as a sixth man successfully, but in the second season, an injury stopped Rannikko from breaking through, and he moved again after two years in Khimki.

On July 31, 2012, he returned to Union Olimpija, where he mostly played off the bench, so he later moved to his home club Kataja.
