The Simca Poissy engine, commonly known as the Simca 1100 engine, was a four-cylinder overhead valve engine developed by Simca for use in its superminis and economy cars, designed by the engineer Georges Martin (V12 Matra Sports engine designer). In spite of its common name, the engine actually predates the Simca 1100 model, and debuted in 1961 in the Simca 1000. It was developed and produced by Simca (subsequently rebranded as Talbot) in the late 1960s at the manufacturer's factory in Poissy, hence its name.

The engine was first designed in a 944 cc (57.6 cu in) form, but was reduced and stretched in order to be used in a variety of models and versions, by Simca, the Rootes Group (its partner company in Chrysler Europe), Simca's final incarnation Talbot and its last parent company Peugeot, who used it until 1991 in its midsize model, the 309. The engine existed in displacements ranging from 0.8 to 1.6 L (777 to 1,592 cc), the biggest one on both sides of the Atlantic, powering the United States-market Dodge Omni/Plymouth Horizon.

Peugeot eventually dropped the engines, replacing them with their own TU family.
