Le Plessis-Robinson (French pronunciation: [lə plɛsi ʁɔbɛ̃sɔ̃] ⓘ) is a commune in the southwestern suburbs of Paris, France.

At the end of the 12th the village was renamed Le Plessis-Raoul, after the local lord Raoul, chamberlain of king Philip II of France.

In 1407 it came into the hands of Jean Piquet de La Haye, who built a castle in the village, now called Le Plessis-Piquet.

In 1682 Jean-Baptiste Colbert, Minister of Finances under Louis XIV had a pond dug which fed the fountains of the nearby Château de Sceaux.

Philippe Pemezec, mayor between 1989 and 2018, started a project to reshape the city, in collaboration with the architects Marc & Nada Breitman, winners of the 2018 Driehaus Prize and part of the New Classical movement.
