The Minotaur IV, also known as Peacekeeper SLV and OSP-2 is an American expendable launch system derived from the Peacekeeper missile. It is being developed by Orbital Sciences Corporation, and is scheduled to make its maiden flight in October 2009, with the SBSS satellite for the United States Air Force.

The Minotaur IV is a four stage vehicle, capable of placing 1,735 kilograms (3,825 lb) of payload into a low Earth orbit. It uses the first three stages of the Peacekeeper missile, combined with a new upper stage. On the baseline version, the fourth stage is an Orion-38, however a higher performance variant, designated Minotaur IV+, uses a Star-38V instead. A five stage derivative, the Minotaur V, is also under development.

Minotaur IV launches will be conducted from SLC-8 at Vandenberg Air Force Base, LP-0B at the Mid-Atlantic Regional Spaceport, and Pad 1 of the Kodiak Launch Complex.
