The Socialist Alternative Politics (Dutch: Socialistische Alternatieve Politiek) is a socialist political party in the Netherlands without parliamentary representation. Many of its members are currently active in the Socialist Party, as for instance a member of the party's board was elected into the Rotterdam municipal council for the SP.
The party was formed as a split from the Pacifist Socialist Party in 1972. It was originally called League of International Communists (Dutch: Internationale Kommunistenbond). It changed its name to Socialist Workers Party (Dutch: Socialistische Arbeiderspartij), then to SAP-Rebel.
The party is the Dutch section of the United Secretariat of the Fourth International. They publish a magazine called Grenzeloos (Borderless).
