Tournebu is a commune in the Calvados department in the Basse-Normandie region in northwestern France.

The de Tournebu family, in medieval times one of the most powerful of the noblesse ancienne, counting among its members chevaliers, seigneurs, crusaders, deans and bishops, derived its name from the lordship of this village. In 1958 in a precedent-setting case, descendants of the de Tournebu family brought suit against another French noble family, the de Foucaults, to prevent them using the de Tournebu name in their title.
