Biff Brewster is the central character in a series of 13 adventure and mystery novels for adolescent boys written by Andy Adams.

The series was published by Grosset & Dunlap between 1960 and 1965.

Most titles were published in hardcover with full color dustjackets, but, like other Grosset & Dunlap juvenile series of the era, production costs were cut by dispensing with the dust jackets and featuring full color cover illustrations in their stead.
