Shinui was a Zionist, secular, and anti-clerical free market liberal party and political movement in Israel. The party twice became the third-largest in the Knesset, but both occasions were followed by a split and collapse; in 1977, the party won 15 seats as part of the Democratic Movement for Change, but the alliance split in 1978, and Shinui was reduced to two seats at the next elections. In 2003, the party won 15 seats alone, but lost them all three years later after most of its MKs left to form new parties. The party was a member of Liberal International until 2009.

The Knesset is the unicameral legislature of Israel.
