The Antonov Serial Production Plant (Ukrainian: Серійний завод «Антонов»), formerly AVIANT (Ukrainian: АВІАНТ), is an aircraft manufacturing company in Kyiv, Ukraine, the serial manufacturing division of the Antonov.

After Kyiv was liberated from the Nazis, the plant was returned there, where until the end of the war it overhauled PO-2 aircraft and assembled Yak-3 and Yak-9 fighters from parts manufactured elsewhere.

After the end of the war the plant was moved to the present location in Sviatoshin, which it had started to develop before 1941.

In 1947-1948 the plant manufactured a pilot batch of five helicopters Mi-1 designed by Mikhail Mil, but the series production was transferred to another enterprise.

The plant produced 18 modifications of the An-2: transport, passenger, agricultural, water bomber for fighting forest fires, a version for fish shoals exploration, a version for scientific and rescue operations in Arctic conditions, etc.

It was the first of a long line of Antonov aircraft with high wings and rear loading cargo ramps.

On April 30, 1974, the plant was renamed once again to be baptised “Kyiv Aviation Production Association”.

From 1985 to 1988 the plant participated in the manufacture of parts for the An-225 "Mriya", designed to carry the shuttle Buran.
