Matthias Ungemach (born 21 May 1968 in Dortmund, North Rhine-Westphalia) is a German rower (6'6"; 100 kg), double World Champion and Olympian.

Other highlights were the win of at Henley Royal Regatta, Good Will Games Seattle, Head of the Charles Boston and 12 German Championships in all boat classes.

[3] In the hours before dawn on 22 February 2020, Ungemach was driving his SUV and towing a 10-meter trailer with rowing shells, on his way to a regatta in Penrith.

As he was in the process of negotiating a traffic calming feature in heavy rain, a 66-year-old pedestrian attempted to cross the roadway behind the SUV, likely not seeing the towed trailer.

[4] Months later, Ungemach was arrested and charged related to the alleged hit-and-run incident, but charges were dropped after an expert report found that the pedestrian had initiated the collision, and that Ungemach likely wouldn't have noticed the impact on the towed trailer.
