Catbalogan City was founded or settled sometime in October 1596, by the priests of the Jesuit Order (Society of Jesus.) Friar Francisco de Otazo, S.J., who arrived in the Philippines in 1596, founded the Catbalogan mission and was thus the first missionary to bring the Catholic faith to the people of Catbalogan. In 1627, Catbalogan was raised to the status of residencia (residence or central house). On October 17, 1768, Catbalogan was ceded to the Franciscans who took over from the Jesuits. The first Franciscan parish priest was Fray Jose Fayo, OFM.

The original name of Catbalogan was Katbalaugan or Kabalaugan. The two syllables of the name are compounds of the prefix kat- or ka- and the substantive noun balaug of the Samar-Leyte Visayan (Waray) language.[citation needed] "Katbalaugan" or "Kabalaugan" means "a place where seafarers, fishermen or sailors take shelter or protection." The old fishing village of Katbalaugan or Kabalaugan was the refuge of people riding in small boats and sailboats when the northwest and southwest monsoons blew during the months of July, August, and September.

During the early days of Spanish colonization of the Philippines, Samar was under the jurisdiction of Cebu. Later, it was declared a separate province. In 1735, Samar and Leyte were united into one province with Carigara, in Leyte, as the capital. The union, however, did not prove satisfactory. In 1768, Samar again became a separate province from Leyte. Since then, Samar has emerged as an independent province with Catbalogan as the capital.

On January 27, 1900, the Americans captured Catbalogan City during the Philippine-American War (1899-1902). On June 17, 1902, a provincial civil government was established on Samar Island by an act of the Philippine Commission with Julio Llorente of Cebu as the first governor of Samar.

On May 24, 1942, during World War II, Japanese forces landed in Barrio Pangdan and occupied the capital. On December 18, 1945, American and Filipino forces liberated Catbalogan from the Japanese.

On June 19, 1965, the Philippine Congress along with the District's Congressman, Felipe Abrigo, approved Republic Act No. 4221 dividing Samar into Western Samar, Eastern Samar and Northern Samar, respectively. Catbalogan thus ceased to be the capital of the whole island-province after enjoying the prestige of being the premier town of Samar for 197 years since 1768. On June 21, 1969, under Republic Act No. 5650, Western Samar was renamed Samar with Catbalogan City still as the capital.

The greatest calamities to occur in Catbalogan City were big fires. The April 1, 1957 conflagration, considered as the most destructive one, caused damage to properties in the amount of thirty million pesos. The next was on May 19, 1969, where damage was estimated at twenty million pesos and the more than century-old Saint Bartholomew Roman Catholic Church was razed to the ground. Paradoxically, like the proverbial Phoenix, each time Catbalogan City suffered under the throes of these calamities, better buildings and infrastructures emerged from the ashes.

As early as 1960, Catbalogan already agitated to become a city. In 1969, Rep. Fernando P. Veloso sponsored House Bill No. 1867 creating Catbalogan into a city. The bill was being deliberated in the Philippine Senate, but the conflagration of 1969 unfortunately caused it to be shelved. Subsequent efforts were made by Catbalogan's and Samar's political leaders such as Mayors Jesus B. Redaja and Coefredo T. Uy, Vice Mayors Gerardo C. Teves and Manuel Van A. Torrevillas, Councilor Art Sherwin L. Gabon and Representatives Antonio Eduardo B. Nachura and Catalino V. Figueroa, respectively, to make Catbalogan's cityhood dream a reality despite strong opposition by the League of Cities of the Philippines.

On March 15, 2007, Catbalogan finally attained its cityhood. Under the sponsorship of Senator Alfredo S. Lim and by virtue of Republic Act No. 9391, Catbalogan was converted into a component city known as the CITY of CATBALOGAN following a unanimous vote by the Philippine Senate. Senator Manuel Villar, Jr. (President of the Senate), Congressman Jose De Venecia, Jr. (Speaker of the House of Representatives), Oscar G. Yabes (Secretary of the Senate), Roberto P. Nazareno (Secretary General, House of Representatives) and Gloria Macapagal-Arroyo (President of the Philippines) were among its signatories. The residents of Catbalogan overwhelmingly ratified this change through a COMELEC plebiscite on June 16, 2007 with over 92% "Yes" votes for cityhood.

However, Catbalogan temporarily lost its cityhood, along with 15 other cities, after the Supreme Court of the Philippines in a very close 6-5 vote granted a petition filed by the League of Cities of the Philippines, and declared the cityhood law (RA 9391) which allowed the town to acquire its city status, unconstitutional.

On December 10, 2008, Catbalogan and the other 15 cities affected filed a motion for reconsideration with the Supreme Court. More than a year later, on December 22, 2009, acting on said appeal, the Court reversed its earlier ruling as it ruled that "at the end of the day, the passage of the amendatory law (regarding the criteria for cityhood as set by Congress) is no different from the enactment of a law, i.e., the cityhood laws specifically exempting a particular political subdivision from the criteria earlier mentioned. Congress, in enacting the exempting law/s, effectively decreased the already codified indicators."[1] As such, the cityhood status of Catbalogan is effectively restored.
