Robin Zentner (born 28 October 1994) is a German footballer who plays as a goalkeeper for Bundesliga club Mainz 05.

He returned to Mainz 05 for the 2017/18 season and played his first competitive game for the first team in October 2017.

In one of his appearances, on November 4, 2017, against Borussia Mönchengladbach, he went viral for an "air kick" after mistaking the penalty spot for the ball following a back-pass, which nearly resulted in a goal.

He suffered a torn cruciate ligament on March 8, 2020, in a Bundesliga match and missed the remainder of the season.

He was named the undisputed starting goalkeeper at Mainz beginning in the 2020/21 season with Müller moving on to SC Freiburg.
