Santa Catalina, officially the Municipality of Santa Catalina, is a 5th class municipality in the province of Ilocos Sur, Philippines. According to the 2015 census, it has a population of 13,945 people.
With an area of 968 hectares (2,390 acres), it is the smallest municipality in the province and the only municipality in Ilocos Sur which has an urban status for all its barangays based on National Statistical Coordination Board (NSCB). 
The feast of the town is celebrated every 25th day of November to celebrate the feast day of Saint Catherine of Alexandria (the town's patron saint).
When the Augustinians were busy with the Christianization of the Ilocos Region, a group of missionaries sailed westward through the river known as "El Mestizo" to the place now called Santa Catalina. They were also looking for fresh water, since the area where he landed yielded only salty water. When they finally found a fresh water spring up north, and were busy quenching their thirst, some of them saw an image of a beautiful lady near the place where he drank, which disappeared after a few minutes. One of them recognized the image as that of Saint Catherine of Alexandria. The Augustinians returned to Villa Fernandina (Vigan) and reported this matter to their superiors. This resulted in the construction of a church in the town with Saint Catherine of Alexandria as the patron saint. It was also declared that Santa Catalina be the name of the town.
A replica of the cross once planted by Salcedo and his party—to signify that the Spanish has conquered the area—stands near the entrance to the municipality.

Poultry, Livestock And Fisheries
The farmers in the locality do not produce livestock or poultry in commercial scale but mostly on the backyard level. Livestock such as cows and water buffalo were being raised to help farmers in their farm needs and serves as working animal. Likewise goats were raised but not in herds and these are for local and home consumption of the farmers. Likewise farmers do not raise poultry in commercial scale but they raised chickens in backyard scale. Most farmers raised fighting cocks which commands higher prices in the market. The total area for fishponds is 53.9021 hectares. These fishponds are almost located in every barangay but the biggest area is at barangay Cabittaogan. Fishponds are classified as a) brackish pond where milkfish are cultured, b) freshwater for the production of tilapia, c) fish cages, d) Municipal fishing grounds which were found within 15 kilometers from the shoreline of coastal barangay and e) communal fishing grounds found in Govantes River.
Sta. Catalina also has manufacturing of concrete well rings-a material used as reservoir in the making of open-dugged wells to irrigate farm lots. There are also service-oriented industries such as gravel and sand businesses that cater to the needs of the Housing Sector and the metal crafts that manufacture sidecars for motorized-tricycles. These industries do have limited employment. One pioneering industry in the locality is the manufacture of Cigars but this industry is already nearing its extinction because of lack of the raw materials (native tobacco) that were used in the manufacture. We do have also the Onion Dehydration Plant an industry that pulverized onion that was exported in different Asian countries. The reason why this dehydrating plant had closed was because of dollar fluctuations.
The main source of income for the locals include farming, fishing and small-scale businesses. As with most Philippine towns, the phenomenon of migrant labor has also contributed much to the development of the town. It is evidenced by the numerous mansions and large houses that dot the area along with the vast expanse of active farms and fields. Sta. Catalina is only four (4) kilometers away from Vigan City, which is the province's center of commerce and trade, and because of this; there are few establishments in the locality. Sta. Catalina has yet to establish a Central Business District (CBD). Residents currently go to Vigan to sell their produce and at the same time buy their household needs and other goods and merchandise that will be retailed in the locality.
