The Buick Skylark is a passenger car formerly produced by Buick. The model was made in six production runs, during 46 years, over which the car's design varied dramatically due to changing technology, tastes, and new standards implemented over the years. It was named for the species of bird called skylark.

Buick is a division of the American automobile manufacturer General Motors (GM). Started by automotive pioneer David Dunbar Buick in 1899, it was among the first American automobile brands and was the company that established General Motors in 1908. Before the establishment of General Motors, GM founder William C. Durant had served as Buick's general manager and major investor. With the demise of Oldsmobile in 2004, Buick became the oldest surviving American carmaker.
