Oyster crackers are small, salted crackers, typically rounds about 0.6 in (15 mm) in diameter, although a slightly smaller hexagonal variety is also prevalent.

They are often served with oyster stew, but oyster crackers do not contain oysters.

Oyster crackers are popular in the northeastern United States, where they are served as an accompaniment to soup, and in the Cincinnati area, where they are frequently served with the city’s distinctive chili.

They are similar in ingredients and flavor to saltine crackers. (source)
