Casiguran [ˌkaːsɪˈguːɾan], officially the Municipality of Casiguran (Tagalog/Kasiguranin: Bayan ng Casiguran; Ilocano: Ili ti Casiguran), is a municipality in the province of Aurora, Philippines. According to the 2024 census, it has a population of 26,855 people.

The municipality is home to the Amro River Protected Landscape.

According to folk legend, the name Casiguran was obtained from the Ilocano term Sigod which means "edge" or "maximum", which is due to the location of the Municipality at the northern edge of Aurora Province. (Another translation & definition of sigod is "soon" or "early") Another legend says that if an unmarried stranger comes to the place, he unavoidably falls in love and marries and most of the time stays for good. The affixation of sigod when converting it to a noun is kasigudan, from which the Hispanized pronunciation "Casiguran" is derived.
