This is a list of members of the sixth legislative session of the Estonian Parliament (Riigikogu) following the 1938 elections (held on 24–25 February 1938). It sat between 7 April 1938 and 5 July 1940, after which Estonia was occupied by the Soviet Union for the first time. Estonia's previous unicameral parliamentary system had been suspended in 1934 and formally dissolved in 1937; on 1 January 1938, the country's Third Constitution came into force, creating a bicameral National Assembly, consisting of the Chamber of Deputies (Riigivolikogu) and the National Council (Riiginõukogu). These were de facto dissolved when the Soviet Union occupied Estonia and established the Supreme Soviet of the Estonian Soviet Socialist Republic.
