Lucban, officially the Municipality of Lucban (Tagalog: Bayan ng Lukban), is a municipality in the province of Quezon, Philippines. According to the 2024 census, it has a population of 54,134 people.

It is dubbed as the Summer Capital, Art Capital, Dance Capital, Tourist Capital, and Rice Capital of Quezon province. The town is also known for its annual Pahiyas Festival, which is held every May 15 in honor of San Isidro Labrador. The municipality is locally the 'Baguio' counterpart of the province.

Legend has it the town derives its name from the lukbán or pomelo tree. Three hunters from neighbouring Majayjay— namely Marcos Tigla, Luis Gamba, and Lucas Mañawa— lost their way following the trail of wild animals at the foot of volcanic Mount Banahaw. Resting under a tree, they saw a crow (uwák) in the tree's branches, and believing this to be a bad omen, they moved to another place and rested again. Whilst in the shade of a large pomelo (lucbán) tree, the trio was attracted to a couple of kingfishers (salacsác) that were singing. Fascinated by the bird's plumage and rhythmic chirps, the superstitious hunters took this as a sign of good fortune and thus settled in the place they named "Lucbán."

Early in the campaign, Japanese forces invaded and occupied Lucban. On December 26, 1941, Filipino and American troops defended Barrio Piis and the attack by the Japanese shifted to the Bataan Peninsula. After Japanese forces occupied the town, they built a military garrison, and the Japanese armed forces were stationed in Lucban. Both local guerrilla and regular troops of the Philippine Commonwealth Army initiated attacks in Lucban from 1942 to 1945.

Sampaloc used to be the Barrio Dingin of Lucban, Quezon consisting of three sitios. It was later renamed Sampaloc because of the presence of a large tamarind tree found in the center of the settlement during the earlier days. The name was also changed in Alfonso Trece for a time to honor the King of Spain. In 1873, Capt. Pedro Cadelina of Lucban recommended changing the barrio into a municipality but due to the lack of residents, it was only made into a “visita”. “Teniente Mayores” were appointed to head the ”visita”, the first of whom was from Polilio, followed by Arcadio Veluya, Laureano Nanola, Silverio Abueva, and Juan Saludades.

Through the efforts of Juan Pineda, Sampaloc became a municipality in 1892. He was elected as the first Capitan. He was succeeded by Diego Gagan followed by Teofilo Daya in 1901. During Daya's term in office, three more barrios from Mauban – Banot, Bilucao, and San Bueno, became a part of Sampaloc through the efforts of Ireneo Domeo, the municipal secretary. The town was also renamed to Sampaloc during this time.
