The Oldsmobile Cutlass Supreme was a mid-size car produced by General Motors for the American market. It was always at the top of the Cutlass range. It began as a trim package, developed its own roofline, and eventually was mechanically divorced from the later, smaller Cutlasses. The Cutlass Supreme name lasted from 1966 until 1997.
When introduced in 1966, it was a four-door hardtop sedan also dubbed the Holiday Sedan by Oldsmobile, the first such bodystyle for Olds' intermediate line. For 1967, the Cutlass Supreme line was expanded into a full series that also included a two-door hardtop coupe (Holiday Coupe), two-door pillared coupe (Sport Coupe), four-door pillared sedan (Town Sedan) and a convertible.
