Condeau (French pronunciation: [kɔ̃do] ^ⓘ) is a former commune in the Canton of Bretoncelles, in the Arrondissement of Mortagne-au-Perche, in the department of Orne (and formerly within Le Perche region) in north-western France: on 1 January 2016, it merged into the new commune of Sablons-sur-Huisne.

Condeau is a town that lies near the river Huisne in Lower Normandy.

The toponym "Condeau" is a diminutive of Condé, a neighboring town name as the confluence (Gaulish condate) of the Huisne and Corbionne rivers.

The French demonym for people who live in Condeau is Condoléen.

In 1789, after the Décret de la division de la France en départements created townships, Condeau became chief town of its canton. In 1801, the canton was abolished.

On 1 January 2016, Condeau merged into Sablons-sur-Huisne as a municipality under by Law Number 2010-1563 of 16 December 2010 on local government reform. The communes of Condeau, Condé-sur-Huisne, and Coulonges-les-Sablons merged and Condé-sur-Huisne became the chief town of the new municipality.

The town council comprises eleven members, including the mayor and two deputies.
