Gechingen was first mentioned in 1110 as a fief of the County of Calw [de] in a document outlining gifts made by local nobility to Hirsau Abbey.

As a result of the Protestant Reformation, Herrenalb Abbey was secularized and its holdings seized by the Duchy of Württemberg, whose government assigned the town to the monastic office [de] at Merklingen.

Gechingen grew slowly in the years after World War II and not see significant urban growth until the 1960s.

[3] A portion of the Federally protected Würm-Heckengäu [de] nature reserve is located in Gechingen's municipal area.

The Federal Ministry of the Interior awarded this coat of arms to Gechingen alongside a municipal flag on 18 July 1955.
