União de Leiria is a Portuguese professional football club based in the city of Leiria, currently competing in the Liga Portugal 2, the country's second division. The club plays its home matches at the Estádio Dr. Magalhães Pessoa and wears blue and white vertical stripes. Founded in 1966, the club's name translates to "Union of Leiria," representing the city. The team's key era arrived in the early 2000s under the management of José Mourinho, who led them to a historic third-place finish in the Primeira Liga in 2002-03 and qualification for the UEFA Champions League. That period featured players like João Paulo and Nuno Gomes. After financial difficulties led to a dramatic decline and restructuring, the modern União de Leiria has fought its way back up the pyramid, re-establishing itself as a stable second-division side with ambitions of a top-flight return. The club is supported by a passionate local fanbase known as "Os Lis." União de Leiria remains a club with a proud history and a determined present.
