Llucmajor (Catalan pronunciation: [ʎuɡməˈʒo, ʎumːəˈʒo]; Spanish: Lluchmayor) is the largest municipality (in terms of surface area) of the Balearic Island of Mallorca.

The population is distributed basically among the town, s'Arenal and the residential areas.

The most important historical event in connection with the town is the Battle of Llucmajor, where in 1349 Peter IV of Aragon defeated his cousin James III of Majorca, resulting in the end of the independent Kingdom of Majorca.

In 1543 Charles V granted the city the right to hold a market on Wednesdays and Fridays.

In the 20th century Llucmajor developed into an industrial centre (especially for shoemaking), and so achieved a degree of prosperity.
