The Lithuanian Popular Peasants' Union (Lithuanian: Lietuvos valstiečių liaudininkų sąjunga, LVLS) was a centre-left political party in Lithuania between 1922 and 1936.
The party's leaders included the third President Kazys Grinius and three-term Prime Minister Mykolas Sleževičius.
At the time the two parties held a combined 19 seats, making it the largest in the Seimas.
The new party emerged as the largest faction in the 1923 elections, winning 16 of the 78 seats.
