A rotation government or alternation government is one of the ways of forming of a government in a parliamentary state. It is a government that, during its term, will see the individual holding the post of prime minister switch (or "rotate"), whether within the same political bloc or as part of a grand coalition. Israel has seen by far the most experience with such a governing arrangement. The governments of Ireland and Bulgaria are now in their first rotation agreement. Usually, this alternation is guided by constitutional convention with tactical resignation of the first officeholder to allow the second to form a new government. Israel, which established the rotation mechanism in 1984, codified it in 2020.

As of 2021^[update], rotation governments have been formed in Ireland, Israel, Malaysia, North Macedonia, Romania, and Turkey. Successful rotations have only taken place in Israel (first with the rotation between Shimon Peres and Yitzhak Shamir, and second with the ascension of Yair Lapid to the office of the Prime Minister of Israel on 1 July 2022, fulfilling the agreement of his coalition government), Ireland (with Leo Varadkar returning as Taoiseach in December 2022) and Romania (with the rotation between Nicolae Ciucă and Marcel Ciolacu in June 2023); in all other cases, either the rotation has not yet taken place or the government has collapsed before it could occur. A rotation government was considered after the 2005 German federal election.
