Buguey, officially the Municipality of Buguey (Ibanag: Ili na Buguey; Ilocano: Ili ti Buguey; Tagalog: Bayan ng Buguey), is a municipality in the province of Cagayan, Philippines. According to the 2024 census, it has a population of 32,351 people.

The site of Buguey was originally called catagayan, a place of many tagay trees. The name came about after Spanish conquistador Juan de Salcedo asked a native what the name of the place was in 1572. Subsequently, the name was shortened to Cagayan, which later became the name for the entire province and region.

Buguey is believed to have originated from the Ibanag word Bugay which means "shipwreck". It was formally established as a Spanish mission in 1596. In 1771, it was raided by Moro vessels from Jolo. According to legend, the Moros looted the town's church and brought its bell with them to sea, whereupon their vessel capsized, leading residents to shout navugay ira (they have capsized).

Buguey is situated 104.08 kilometres (64.67 mi) from the provincial capital Tuguegarao, and 589.23 kilometres (366.13 mi) from the country's capital city of Manila. It lies along the Buguey Lagoon, one of the largest estuaries in Cagayan.

Buguey is politically subdivided into 30 barangays. Each barangay consists of puroks while some have sitios.

In the 2024 census, the population of Buguey was 32,351 people, with a density of 200 inhabitants per square kilometre or 520 inhabitants per square mile.
