The Alda was a French automobile created by Fernand Charron of CGV; it was manufactured between 1912 and 1922. The car had a dashboard radiator and a 3187 cc four-cylinder engine that was claimed to be capable of going "6 to 47 mph in top gear" (9.7-76 km/h). Cars were available with the Henriod rotary valve system; another version featuring six cylinders was also offered. Post-war, the four was the only model offered, though it was rebored to 3563 cc.

The Alda is most remarkable, if at all, for the manner in which its name was chosen. "ALDA" was an acronym, standing for "Ah - La Délicieuse Automobile!". The name was invented by the readers of the magazine l'Auto; this, to be sure, is a highly unusual, if not unique, manner of choosing the name of an automotive marque.
