The Gold Coast Historic District is a historic district in Chicago, Illinois. Part of Chicago's Near North Side community area, it is roughly bounded by North Avenue, Lake Shore Drive, Oak Street, and Clark Street.

The Gold Coast neighborhood grew in the wake of the Great Chicago Fire. In 1882, millionaire Potter Palmer moved to the area from the Prairie Avenue neighborhood on the city's south side. He filled in a swampy area which later became Lake Shore Drive, and built the Palmer Mansion, a forty-two room castle-like structure designed by Henry Ives Cobb and Charles Sumner Frost. Other wealthy Chicagoans followed Potter into the neighborhood, which became one of the richest in Chicago.

In the late 1980s, the Gold Coast and neighboring Streeterville comprised the second most-affluent neighborhood in the United States, behind Manhattan's Upper East Side. Today, the neighborhood is a mixture of mansions, row houses, and high-rise apartments. Highlights include the Astor Street District and the James Charnley House.

The district was added to the National Register of Historic Places in 1978.

The nearby East Lake Shore Drive District and parts of northern Streeterville and the Magnificent Mile near the lake also may be considered part of the Gold Coast (such as the area around the 860-880 Lake Shore Drive Apartments), even if not technically in the historic designation. The mayor's office map extends the Gold Coast south to the area of Northwestern University's Chicago campus.

As of 2011, Gold Coast ranks as the 7th richest urban neighborhood in America with a median household income of $153,358.
