Unión Deportiva Las Palmas, commonly referred to as UD Las Palmas or Las Palmas, is a professional football club based in Las Palmas de Gran Canaria, Canary Islands, Spain. The club competes in La Liga, the top division in the Spanish football league system. Nicknamed Los Amarillos, the club was founded on 22 August 1949 as a result of a merger between five clubs in the Canary region. The club initially played in the Estadio Insular before hosting their home matches at the Estadio de Gran Canaria in 2003.

Las Palmas have been Segunda División champions four times, in 1953–54, 1963–64, 1984–85 and 1999–2000, and have won the Segunda División B twice, in 1992–93 and 1995–96. They have been runners-up in La Liga once, in 1968–69, and runners-up in the Copa del Rey, in 1977–78. Las Palmas is the only side in Spanish football to achieve back-to-back promotions to La Liga in their first two seasons. They had a 19-year run in the competition, ending in 1982–83 and has been promoted to La Liga on four additional occasions since that time, achieving it recently in 2022–23.

Since its foundation, the club has played with yellow and blue as their primary and secondary colours. They have a fierce rivalry with neighbouring island Tenerife, with whom they contest the Canary Islands derby. The two clubs are among the most isolated professional football clubs in Europe since they play their away games on the distant Spanish mainland.
