Senate of the Republic (Turkish: Cumhuriyet Senatosu) was the upper house of Turkish Parliament between 1961 and 1980. It was established with the Turkish constitution of 1961 and abolished with the 1982 constitution, although it did not exist after 12 September 1980 as a result of the 1980 coup d'état.
Although the Turkish Parliament was established in 1920 to replace the older Ottoman Parliament, which had an upper Senate and lower Chamber of Deputies, the new parliament was composed of a single chamber. The Turkish constitution of 1961 introduced an upper house called the Senate of the Republic, or Senate for short. The name Grand National Assembly of Turkey (Turkish: Türkiye Büyük Millet Meclisi) referred to the entire parliament including both houses. However, the activities of the both houses of the parliament were suspended after the 1980 Turkish coup d'état. Under the 1982 constitution, the Senate was abolished.
