Contract Sejm (Polish: Sejm kontraktowy) is a term commonly applied to the "Sejm" (parliament) elected in the Polish parliamentary elections of 1989. The contract refers to an agreement reached by the Polish United Workers' Party and the Solidarity (Solidarność in Polish) movement during the Polish Round Table Agreement. The final agreement was signed on April 5, 1989. As a result, real political power was vested in a newly created bicameral legislature and in a president who would be the chief executive. Solidarność became a legitimate and legal political party.
