Siamese general election, 1946

General elections for the National Assembly were held in Siam on 6 January 1946. In the first elections since the Second World War, a total of 2,091,788 votes were cast and voter turnout was 32.5%. A second round of elections was held in 47 provinces on 5 August in order to increase the number of MPs to the number set in the constitution.

At the time there were no political parties, so all candidates ran as independents. There were unofficial affiliations. Supporters of Pridi Banomyong (Sahachip Party and the Constitutional Front) took 57 seats, the Democrat Party took 18 seats and a further seven seats went to unaffiliated representatives.
