Rosenthal is a small town in southeast Waldeck-Frankenberg district in Hesse, Germany.

Rosenthal was founded in 1327 as a Mainz town and outpost in the dispute over the Hessian fief, but nevertheless passed to the Landgraviate of Hesse in 1464.

As part of Hesse's municipal reforms in the early 1970s, the heretofore independent communities of Roda and Willershausen were amalgamated with Rosenthal.

The town council's 15 seats are apportioned thus, in accordance with municipal elections held on 26 March 2006: Note: Bürgerliste Roda is a citizens' coalition.

Rosenthal's civic coat of arms might heraldically be described thus: In gules a six-spoked wheel argent surrounded per square by four roses Or with centres azure and sepals vert.
