This is a list of public holidays (national or otherwise) in Chile; about half of them are Christian holidays.

On January 28, 1915, President Ramón Barros Luco promulgated Law 2,977,^[3] which organized all available information regarding holidays celebrated in Chile. It established or retained the following holidays:

1. Sundays year-round.
2. January 1 (Feast of the Circumcision of Christ at the time; New Year in the late 20th and 21st centuries), June 29 (Feast of Saints Peter and Paul), August 15 (Assumption of Mary), December 8 (Immaculate Conception), December 25 (Christmas Day), and the movable holidays of the Ascension of Jesus Christ and Corpus Christi.
3. Fridays and Saturdays during Holy Week.
4. September 18, Establishment of the First Government Junta in 1810.
5. September 19 and May 21, in celebration of the achievements of the Army and the Navy.
6. The day of election of electors of the President of the Republic.

The same law abolished, by omission, four religious holidays: Epiphany (Adoración de los Santos Reyes, January 6), Carnival (Carnaval, movable), Annunciation (Anunciación del Señor, March 25), and Nativity of the Virgin Mary (Natividad de la Virgen, September 8). It also shortened the national independence holiday to two days (until 1914, they occupied September 18, 19, and 20).

On November 14, 1921, President Arturo Alessandri Palma promulgated Law 3,810,^[4] designating October 12 (Columbus Day) as a holiday. On April 30, 1931, President Carlos Ibáñez del Campo promulgated the Decree Enforceable as Law (Decreto con Fuerza de Ley) 130, marking May 1 (May Day) as a holiday.

In 1932, Provisional President Bartolomé Blanche reinstated the September 20 holiday,^[5] which remained in effect until 1944.^[6] In 1968, the holidays of Saint Peter and Saint Paul, Ascension of Jesus Christ, and Corpus Christi were eliminated by Article 144 of Law 16,840.^[7] The Catholic Church agreed to celebrate them on the nearest Sunday. September 11 (the day of the military coup in 1973) was established as a holiday (Día de la Liberación Nacional, "Day of National Liberation") by the military regime in 1981.^[8] In 1998, it was replaced by the Día de la Unidad Nacional ("Day of National Unity"),^[9] observed on the first Monday in September. In March 2002, the latter was abolished.^[10] The holiday on June 29 (Feast of Saints Peter and Paul) was reinstated in September 1985.^[11] In 1987, during a visit by Pope John Paul II, Corpus Christi was reinstated^[12] (although the Church continued to observe the holiday on the nearest Sunday^[13]).

On March 10, 2000, Law 19,668^[14] moved the Feast of Saints Peter and Paul, Columbus Day, and Corpus Christi holidays to the preceding Monday if they fell on a Tuesday, Wednesday, or Thursday, or to the following Monday if they fell on a Friday. Additionally, the designation of Columbus Day was changed from Aniversario del Descubrimiento de América to Día del Descubrimiento de Dos Mundos ("Discovery of Two Worlds' Day"), which was an obvious adaptation of the then-recent ubiquitous Encuentro de dos mundos ("The Meeting of Two Worlds") slogan.^{[15][16][17][18][19]}

On January 6, 2007, Law 20,148^[20] replaced Corpus Christi with Our Lady of Mount Carmel, to be observed on July 16, starting that year. On September 14, 2007, Law 20,215.^[21] declared holidays for all September 17s falling on a Monday and all September 20s falling on a Friday. On October 11, 2008, Law 20,299^[22] established Reformation Day on October 31 as a national holiday, starting that year. This holiday is moved to the preceding Friday if it falls on a Tuesday or to the following Friday if it falls on a Wednesday. On April 30, 2013, Law 20,663 established the regional Battle of Arica holiday, to be observed only in the Arica and Parinacota region.^[23] On December 30, 2016, Law 20,983^[24] declared as holidays those days that are Monday, January 2, or Friday, September 17. On June 19, 2021, Law 21,357^[25] declared the Winter Solstice as a holiday, honoring Chile's aboriginal peoples (pueblos originarios).

In addition to yearly holidays, presidential elections have been declared holidays since 1901, as mandated by successive versions of the General Elections law (Law 18,700,^[26] being the current one; see laws 1,464,^[27] 1,752,^[28] 2,977,^[3] decree-law 542,^[29] 6,250,^[30] 6,834, 9,334, and 12,891). Since the late 20th century, parliamentary and municipal elections are also public holidays (see Law 18,700^[26]). Censuses, held every ten years, have been declared holidays since 1982; that year's census and 1992's were so due to ad-hoc laws;^[31][32] censuses taken from 1992 onwards are declared holidays due to a reform in the Census law.^[33] (This did not occur in 2012, where the census was carried out over two months, using a different methodology.)^[34]
