The Buick Skylark was a passenger car produced by the Buick division of General Motors. The model was made in six production runs. In each run, the car design varied dramatically due to changing technology and tastes, as well as new standards implemented over the years.

Introduced to mark Buick's 50th anniversary, the Skylark (a name previously used by short-lived Hupp for its sporty 1939 Cord 810-based Skylark) was one of three specialty convertibles produced in 1953 by General Motors; the other two were the Oldsmobile Fiesta and the Cadillac Eldorado. All three were limited-production vehicles promoting General Motors' design leadership. Of the three, the Skylark had the most successful production run with 1,690 units. This was considered an amazing sales feat, since the car had a list price in 1953 of slightly in excess of US$5,000. However, many of these vehicles languished in dealer showrooms and were eventually sold at discount.

There were only minor changes to the lineup for the 1997 model year, which was the last year that it would be available to the public in showrooms. A single-model 1998 Skylark sedan was produced for fleet-only sales, mostly to auto rental companies. Most of these 1998 models, the last year that Buick used the Skylark name and produced a compact car, were eventually resold to the general public as used cars. Buick never provided a direct replacement for the car and potential buyers of an entry-level Buick were directed to the mid-sized Century. The Skylark production line in Lansing was retooled to build the 2000-2003 Chevrolet Malibu.
