Evelin Jahl (née Schlaak and later Herberg, born 28 March 1956) is a German former discus thrower, who won two Olympic gold medals representing East Germany.

In 1976 she won the women's discus throwing event at the Montreal Summer Olympics defeating favourite and world record holder Faina Melnik.

Two years later Jahl defended the Olympic title in Moscow, again relegating Vergova, also competing under her married name (Petkova), into second place.

Shortly after her retirement, she married the swim trainer Harald Herberg but she soon divorced him.
