Soyuz 30 (Russian: Союз 30, Union 30) was a 1978 crewed Soviet space flight to the Salyut 6 space station. It was the sixth mission to and fifth successful docking at the orbiting facility. The Soyuz 30 crew were the first to visit the long-duration Soyuz 29 resident crew.

Soyuz 30 carried Pyotr Klimuk and Mirosław Hermaszewski, the first (and to date, only) Polish cosmonaut, aloft.
