The Reformed Political Party (Dutch: Staatkundig Gereformeerde Partij [ˌstaːtˈkʏndə(x) xəˌreːfɔrˈmeːrdə pɑrˈtɛi], SGP) is a conservative Reformed Christian political party in the Netherlands. The SGP is the oldest political party in the Netherlands existing in its present form, and has been in opposition for its entire existence. Since 1925, it has won between 1.5% and 2.5% of the votes in general elections – invariably receiving 2–3 seats in the House of Representatives, making it the country's most stable political party in terms of representation. Owing to its orthodox political ideals and its traditional role in the opposition, the party is considered a testimonial party. Since 2023 its leader has been Chris Stoffer.
