Dasol, officially the Municipality of Dasol (Pangasinan: Baley na Dasol; Ilocano: Ili ti Dasol; Tagalog: Bayan ng Dasol), is a municipality in the province of Pangasinan, Philippines. According to the 2020 census, it has a population of 31,355 people.

Dasol is a popular town for the production of commercial salts. Seawater is fed into large ponds and water is drawn out through natural evaporation which allows the salt to be harvested. Dasol Bay occupies the whole coastline of Dasol and it is where the town gets its saltwater.

The town got its name from the medicinal herb "dosol" which abound in the locality during the Spanish period. The leaves of this herbal plant are greenish and oval in shape. It is a tuber relatively very low in height. It was commonly used to cure infected wounds, but was found to have the unusual characteristic of miraculously disappearing (abandoning its post) for unknown reason never to be located again. Its name was frequently mispronounced as Dasol by the Spaniards, so that when the place was established as municipality in the 19th century, Dasol became its official name.

As early as 1878, Dasol was part of municipality of San Isidro de Potot, which also include the present-day municipalities of Mabini (at that time was named as Barrio Balincaguin), and Burgos, in Zambales province. At that time, there were few people lived in Dasol. Balincaguin was the most thickly populated barrio and later became an independent municipality. The people, in their desire for better living conditions, moved to the south-west. They found good fishing grounds and they decided to stay along the coast in the barrio of Uli, Dasol. Dasol was repopulated by the Ilocano settlers from Paoay, Ilocos Norte headed by Don Matias Guiang in 1830.

A revolutionary group was organized in the Central Luzon on January 14, 1898, under General Francisco Macabulos. The Pangasinan sub-group was headed by Vicente del Prado, who together with Daniel Maramba reached an understanding to launch an attack on Spanish situations. On March 7, 1898, a simultaneous attack was suddenly made upon convents in number of towns of western Pangasinan (then as northern Zambales). Areas of San Isidro de Potot, Dasol (proper), and Eguia were among attacked. The Spanish detachments in these towns and around fifty Spanish friars were defeated.

On November 7, 1903, the northern part of Zambales was annexed to the province of Pangasinan by virtue of Act No. 1004. The municipalities ceded were Alaminos, Bolinao, Anda, San Isidro de Potot, Bani, Agno, and Infanta. Townsfolk cited alleged lack of concern for the towns' interest and welfare by the Zambales provincial government and was encouraged to join Pangasinan province. However, for allegedly the same reason, there was a movement to rejoin Zambales, which clamor was aroused by the incumbency of then President Ramon Magasaysay, a Zambales-born president in the middle of the 1950s. This proposal was wiped out completely when Governor Aguedo Agbayani of Pangasinan became the governor.

In 1911, by virtue of Executive Order No. 25, signed by Governor-General William Cameron Forbes, Dasol seceded from San Isidro de Potot, San Isidro de Potot was renamed as Burgos (in honor of José Apolonio Burgos) and Balincaguin was renamed as Mabini (in honor of Apolinario Mabini).

Ever since its creation, the boundaries of Dasol with the municipalities of Burgos, Mabini and Infanta remain vague, for what the leaders of Dasol had claimed to be the boundaries then agreed upon and as allegedly borne out by records, are no longer respected by the respective officials of said adjoining municipalities. Instead, they have encroached into Dasol's domain. During the incumbency of Mayor Liceralde, he made an attempt to settle Dasol's boundary with Mabini, but even after two separate conferences between the officials of the two towns were already had, each group was adamant in its own version. Considering that there was no visible sign of a probability for an amicable settlement of the dispute, the idea was abandoned so as to give way to court battle. He allegedly said that it was time-consuming to gather relevant documentary evidence (parol evidence no longer available due to the death of reliable witnesses) that would clinch the case for Dasol. The same appears to be true with respect to the other boundary conflicts.

Dasol Bay witnessed several naval battles in World War II. On August 23, 1944, while searching for new targets, the American submarines USS Harder and USS Hake were attacked by Kaibokan CD-22 and PB-102 (ex-USS Stewart (DD-224)). Thinking that it was just a Japanese minesweeper and a three-stack Thai destroyer Phra Ruang, the Japanese vessel operated in consort with the anti-submarine vessel attacked and sank the Harder through with depth charges. The Hake was also attacked but escaped and arrived at Fremantle Harbor, Australia on September 24, 1944.

On November 6, 1944, while guarding convoy Ma-Ta 31, the Japanese cruiser Kumano was attacked by a US submarine wolf-pack consisting of the Batfish, the Guitarro, the Bream, theRaton and the Ray. In all, the American submarines launched 23 torpedoes towards the convoy, two of which struck the Kumano. The first hit destroyed the ship's recently replaced bow, and the second damaged its starboard engine room. The Kumano escaped and was towed to Dasol Bay by the cargo ship Doryo Maru, and from there the ship was moved to the beach and underwent repairs. On November 25, 1944, the Kumano came under aerial attack by aircraft launched by the USS Ticonderoga. Five torpedoes and four 500 pound bombs struck the ship, and rolled over and sank in about 31 m (100 ft) of water.

Dasol is a small town in western Pangasinan, situated in a plateau. It is bounded on the north by the municipalities of Burgos and Mabini, the mineral-rich Zambales mountains in the east, the municipality of Infanta on the south, and the vast South China Sea on the west. It has an area of about 230 square kilometers.

Dasol is 302 kilometers (188 mi) north from Metro Manila and 96 kilometers (60 mi) from Lingayen.

Dasol is politically subdivided into 18 barangays. Each barangay consists of puroks and some have sitios.

Dasol had seven barrios (now called barangay) when it was created. These were Tambobong, Tanobong, Uli, Malacapas, Bongalon, Alilao and Poblacion. Eguia was then part of Infanta and was annexed to Dasol in 1925. As years went by and due to its increasing population, two more barrios were created. Eguia was divided to form other three barangays namely Macalang, Viga and Tambac. Then came the time when Tambobong was to create Magsaysay and Tanobong (Malimpin) was divided to create San Vicente. Later, Bongalon (Hermosa) was divided to create Petal out of its two sitios Penec and Espital and from Alilao, two more barangays were formed now known as Amalbalan and Gais-Guipe. The sitios of Macalang, Pantol, Tapac and Pagdagaan were constituted into a barrio of Macalang by virtue of Republic Act 1707.

No record has been found regarding the reign of a governardorcillo in this municipality but records show that there was already an organized government, with Santos Jimenez, Vicente Liceralde, Gaspar Estrada and Pedro Estrada as early capitan municipáles.

Cornelio Estrada was the capitan municipál from 1898 until 1900. At the height of the Katipunan resistance against the Americans, Francisco Bernal was the capitan municipál.

During the time San Isidro Putot was established, the town had been under three rulers, who ruled in different terms, namely: Lucas Bonilla (1899–1901), Nazario Nacar (1901–1903), and Paulino Mendoza (1904–1908).

When Dasol municipality was created, Apolonio Casipit was its first president. He was succeeded by Leandro Cristobal from 1912 to 1916. Calixto Tobias was the municipal president from 1916. In 1918, Tobias was assassinated by an unknown assailant. His unexpired term was served by his vice mayor, Severino delos Reyes. In the following election, Apolonio Casipit won and served his second term from 1918 to 1920. Succeeding him was Pedro dela Rosa from 1921 to 1925.

In the years 1925 to 1932, Marcelo Jimenez was elected and served for two consecutive terms. In the following election, Flaviano Cristobal served as the last Municipal President from 1932 to 1935. He was elevated as Dasol's first Municipal Mayor, when the Commonwealth Government was established. He was followed by Juan Castro (1937–1939). Mayor Castro failed to serve the entire period of his term due to health conditions making his vice mayor, Emiliana R. Jimenez as Acting Municipal Mayor for the unexpired term (1940). In the next election, Flaviano Cristobal ran again and won, making him as the Municipal Mayor of Dasol at the outbreak of the second world war. He was forced to vacate the office in 1944 when he joined guerilla movement intervention. His vice mayor, Teodoro Milgar served as acting mayor for the unexpired term. When Philippine Independence came in 1946, Marcelo A. Jimenez was appointed by President Roxas as Acting Municipal Mayor. Like Mayor Castro, Mayor Jimenez failed to serve the entire period of his term in the same year.

Isidro Bustria served the unexpired term of Marcelo A. Jimenez from 1946 until 1948. In the 1948 election, Damaso E. Rivera won and served as municipal mayor. In 1950, Rivera failed to finish his term and his vice mayor, Segundo Basuel, served his unexpired term. In 1952, Cristino R. Jimenez won and served for four consecutive terms (1952–1967), winning three re-elections. In 1968, Ramon G. Liceralde won as mayor. 1976 local elections was suspended due to the existence of martial law. Liceralde, was so far the only lawyer-mayor of Dasol. In 1978, Benjamin Ochotorena was appointed Municipal Mayor until 1980. Ludovico R. Espinosa was elected and served as mayor from July 1980 until the government reorganization on June 10, 1986, by President Corazon Aquino.

In the May 11, 1992 elections, Espinosa was defeated by Sergio N. Jimenez. Jimenez also defeated Espinosa in two successive elections (1995,1998). Due to term limits set by the Philippine Local Government Code of 1991, Sergio Jimenez gave way to his wife, Angelita Ocampo-Jimenez to run for the 2001 elections. Mrs. Jimenez won beating Vice Mayor Moises Alejos. In the 2004 elections, Mrs. Jimenez won her second term unchallenged. In the 2007 elections, Councilor Noel Nacar challenged Jimenez and won as new mayor of Dasol. He then served for three consecutive terms.
