Charles-Marie de Trolong du Rumain (30 September 1743 – 10 August 1780) was a French Navy officer and colonial administrator who served as the governor of Saint Vincent in 1779.

He took part in the War of American Independence, notably commanding the 10-gun cutter Curieuse which, along with Iphigénie, captured HMS Lively on 10 July 1778.

The next year, he directed the Capture of Saint Vincent and became colonial governor of the island.

In September 1779, he took part in the Siege of Savannah, captaining the 32-gun Chimère.

On 10 August 1780, Nymphe encountered HMS Flora off Ushant, and Trolong du Rumain was mortally wounded in the ensuing engagement.
