Maisons Jaoul are a celebrated pair of houses in the upmarket Paris suburb of Neuilly-sur-Seine, designed by Le Corbusier and built in 1954–56. They are among his most important post-war buildings and feature a rugged aesthetic of unpainted cast concrete "béton brut" and roughly detailed brickwork.

The buildings were drawn in 1937 but were only built postwar for André Jaoul and his son Michel. They were for a time owned by English millionaire Peter Palumbo, Baron Palumbo. They now belong to two sisters who live there with their families. The Maisons Jaoul have been protected by the French government as historical monuments since 1966, at the request of André Malraux.

The son Michel (or Jacques Michel) Jaoul worked as an architect in Le Corbusier's office and in 1988 was in charge of the renovation of the houses. The construction of these vaulted houses signals a new trend in Le Corbusier's work, and the Maisons Jaoul can be considered his first "New Brutalist" work.
