União dos Palmares is a municipality located in the Brazilian state of Alagoas. Its population was 65,790 (2020) and its area is 428 km². Surrounding agricultural land is largely dedicated to sugar cane and cattle. At one time, when the city was an active rail stop with regular passenger service, it was named simply União due to its rail junction joining Alagoas and Pernambuco. The name was changed in 1944 to reflect its historic significance. The city is increasingly seeing domestic and foreign tourist drawn by historical and natural features that are now protected in Parque Nacional Serra da Barriga and Parque Memorial Quilombo dos Palmares.

The city of União dos Palmares has a historic importance to Afro-Brazilians. On a nearby hill was a mocambo or, in more recent terms, a quilombo. These were centers of African slaves fleeing and resisting slavery. Known as the Quilombo dos Palmares this was the largest and most organized of the many quilombos in Brazil. The most famous figure of the Quilombo dos Palmares was Zumbi dos Palmares. The quilombo reached a population somewhere around 30,000 composed of former slaves and some Amerindian allies. Between 1672 and 1696 it withstood repeated attacks by colonial forces until it fell to regular forces with artillery.
