Signal de la Mère Boitier, Mountain summit in Saône-et-Loire, France

Signal de la Mère Boitier is a 758-metre summit on the commune of Tramayes in Saône-et-Loire, one of the culminating points of the Mâconnais mountains alongside Mont Saint-Cyr. Its wooded hill rises above a pasture and a long low building with a reddish roof; the western talus slopes are abrupt while the eastern flanks fall gently.

The summit was formerly called la mure Boitier, a toponym in which mure may refer to an ancient settlement site. A legend attributes the name to a local innkeeper murdered in the stagecoach era. The peak gives its name to the communauté de communes Saint-Cyr Mère Boitier entre Charolais et Mâconnais.

The summit gave its name to the communauté de communes Saint-Cyr Mère Boitier entre Charolais et Mâconnais. The Tramayes brass band is called Les enfants de la Mère Boitier, and a mountain-bike circuit is named la Trans de la mère Boitier.

The orientation table at the top is reached by a fairly steep path. Below the summit lie a picnic area and the 1.6-kilometre "dessous de la mère boitier" trail. The summit rises above the surrounding land for at least 6 kilometres in every direction.

The summit's name survives in local use: the Tramayes brass band calls itself Les enfants de la Mère Boitier, and a mountain-bike circuit is named the Trans de la mère Boitier. The commune community of Saint-Cyr Mère Boitier entre Charolais et Mâconnais also takes its name from the peak.
