This article lists the Imerina monarchs, from the earliest origins of the Merina monarchy until the French conquest of the Merina Kingdom during the Second Madagascar expedition.

Below is a list of the line of Merina monarchs that ruled in the Central Highlands of Madagascar and from whom were issued the first true monarchs of a united Madagascar in the 19th century. Before the uniting of Madagascar, succession was based on the current monarch's designation of an heir, typically from among his or her own children. As such, the list below represents a direct genealogical line from the last 19th-century queen of Madagascar to some of the earliest known rulers identified in the 15th century or before. Prior to the 16th century, detailed information about the names and dates of Merina rulers becomes less consistent. Genealogy in this early period are derived primarily from oral history, while later names and dates are verifiable from primary sources. These combined sources provide the following list of Merina rulers preceding Andrianampoinimerina's unification of Imerina in the Central Highlands and his son Radama I's successful conquest of the majority of Madagascar, bringing the island under his rule.

Asterisks denote names drawn from oral history without substantive evidence to verify the ruler's life or reign, viz., legendary or semi-legendary monarchs.
