The Oldsmobile Omega was a compact car sold from 1973 through 1984 by the Oldsmobile division of General Motors. There were two generations of Omegas, both based on popular Chevrolet models, and both using the GM X platform architecture:

• 1973-1979 - rear-wheel drive, related to the Chevrolet Nova.
• 1980-1984 - front-wheel drive, related to the Chevrolet Citation.

This car was the top of the X-body line along with Buick's Apollo and Skylark, having more luxury trimming, more noise insulation, rear anti-roll bars, and other features not found on the Nova.

During the 1975-76 model years, the top engine choice was a 350 cu. in. (5.7 Liter) V8 from GM's Buick division. During that time, the base engine was the 115 hp (86 kW) 250 cu. in. (4.1 Liter) inline 6 from Chevrolet, until 1978 when it was dropped in favor of the lighter 110 hp (82 kW) Buick 231 V6 . It saw few changes through its life being limited mostly to the front end (3 different grilles) and to the rear lights, changing the number of lenses through the years. The Oldsmobile 260 V8 (4.3 Liter) was available as an option from 1975-79.

The X-bodies were all-new front-wheel drive cars for 1980. Engine choices were now limited to Pontiac's Iron Duke and the new corporate 2.8 L LE2 V6 designed specifically for this platform.

Unlike the Chevrolet Citation, which the car was based upon, the Omega range consisted of 2-door and 4-door notchback sedans, with upright styling and a distinctive split grille.

For 1985, the Omega was replaced by the N-body Calais.
