Bagoóng (Tagalog pronunciation: [bɐɡuˈʔoŋ]; buh-goo-ONG) is a Philippine condiment partially or completely made of either fermented fish (bagoóng isdâ) or krill or shrimp paste (bagoóng alamáng) with salt. The fermentation process also produces fish sauce known as patís.

The preparation of bagoóng can vary regionally in the Philippines.

Bagoóng is usually made from a variety of fish species, including the following:

Bagoóng made from fish is encompassed by the term bagoóng isdâ (lit. "fish bagoong") in Luzon and northern parts of the Visayas. They can be distinguished further by the type of fish they are made of. Those made from anchovies are generally known as bagoong monamon or bagoong dilis and those from bonnetmouths as bagoong terong.

In the southern Visayas and Mindanao, fish bagoong made from anchovies is known as guinamos (also spelled ginamos). Larger fermented fish are known as tinabal.

Bagoong can also be made from krill. This type of bagoong is known as bagoong alamang. It is called uyap or alamang in the southern Philippines, aramang in Ilocos and parts of Northern Luzon, and ginamos or dayok in western Visayas.

In rarer instances, it can also be made from oysters, clams, and fish and shrimp roe. A kind of bagoong made in the town of Balayan, Batangas is also known as bagoong Balayan.

Vegan Bagoong Alamang is a type of fermented Philippine condiments abstaining from animal product. Instead, squash, morinaga and other vegetables are used.
