The Omsk Engine Design Bureau is an aero engine design bureau. It was originally situated in Moscow in the Soviet Union, but was evacuated in 1941. Operations were moved to a "site of farm machinery". The Bureau returned to Moscow and became independent on 5 July 1947 and was renamed "OKB-20". The bureau absorbed OKB-29 in 1963 and in 1966 was renamed Mashinostoitel'noe KB (MKB). Since 1994, it has been known as Omskoe mashinstroitel'noe KB (or OMKB).
Although it has had many chief designers and directors, many of the engines from this bureau are known by the name Glushenkov, named for V.A. Glushenkov, a designer from 1963.
