Hagen Melzer (born 16 June 1959, in Bautzen) is a former East German middle and long-distance runner who specialised in the 3000 m steeplechase.

A year later he won the silver medal at the 1987 World Championships in Rome, where he set a national record at 8:10.32 minutes.

This remained his career best time, and places him second on the German all-time performers list behind Damian Kallabis, who ran in 8:09.48 minutes in 1999.

Melzer won seven East German national titles, in 1980, 1983 and the years 1985–1989.
