The Citroën B10 is an automobile produced by Citroën at André Citroën's factory in central Paris between 1924 and 1925.

The B10 was manufactured using modern mass production technologies which were applied by Citroën and still, at this point, by no other French auto-maker; although by now, across the river Rhine, Opel were also copying the assembly line approach (and also copying one of Citroën's models).

The Citroën B10 was in many respects similar to the manufacturer's "B2" model. What marks it out as different is its use of an "all-steel" ("tout-acier") body. The B10 was the first European car maker to apply the pressed steel technologies, developed by Ambi-Budd, and which during the next fifteen years would transform the economics of automobile production across Europe.

The Citroën B10 shared its chassis and engine with the B2, and was produced in parallel with that car. Both models were replaced by the Citroën Type B12 which made its first public appearance at the 19th Paris Motor Show in October 1924.

The size of the 4-cylinder engine remained at 1,452 cc, and as with the earlier model, the B10 was sometimes known as the Citroën 10HP (or 10CV), the HP in the suffix being a reference to its fiscal horsepower, a number computed according to the cylinder diameters and used to define its taxation class. From October 1924 all Citroën came with "comfort tyres" ("pneus confort") included in the price.

The "Type B10" exhibited at the show in October 1924 used a "Conduite Intérieure" (two-box saloon/sedan) all-steel body and was priced by the manufacturer at 25,000 francs. Citroën's "Torpedo" bodied version of its 10HP model still came with a traditional timber frame body and was accordingly designed a "Type B2": this car was listed by the manufacturer at 18,000 francs. The price of the "Torpedo" bodied car rose to 19,000 francs and it became a "Type B10" in spring of 1925 when it, too, received "all-steel" bodywork.
