Thomas Schönlebe (born 6 August 1965) is a retired East German track and field athlete who competed in the 400 metres.

In that race, he set a European record of 44.33 seconds which stood for 35 years before it was broken by Matthew Hudson-Smith in August 2023.

A year earlier, Schönlebe had finished second at the 1986 European Championships in Stuttgart behind Roger Black.

One of his last achievements was the third place at the 1993 World Championships in Stuttgart with the (now unified) German 4 × 400 m relay team.

Note: Schönlebe qualified for the 1988 European Indoor final but withdrew.
