The Blue Bird All American is an American school bus produced by the Blue Bird Corporation (originally Blue Bird Body Company). Introduced in 1948, the All American is the longest-produced transit-style (Type D) school bus by an American manufacturer. While not the first to use the transit-style design, the All American popularized it through most of the United States during the mid-20th century. It is produced in both a front engine-version and a rear-engine version.
