The Eldorado is a two-door personal luxury car manufactured and marketed by the Cadillac Division of General Motors from 1953 to 2002. Competitors included the Lincoln Mark Series and the lower-priced Buick Riviera and Oldsmobile Toronado.

The Eldorado was at or near the top of the Cadillac line during early model years. The original 1953 Eldorado convertible and the Eldorado Brougham models of 1957–1960 were the most expensive models that Cadillac offered those years, and the Eldorado was never less than second in price after the Cadillac Series 75 until 1966.

Beginning in 1961, Cadillac marketed an upper trim level named after the French coastal resort, the Eldorado Biarritz.
