Cape May is a peninsula and island (divided by a narrow channel); the southern tip of the island is the southernmost point of the U.S. state of New Jersey. The peninsula resides in Cape May County and runs southwards from the New Jersey mainland, separating Delaware Bay from the Atlantic Ocean. The cape is named for Cornelius Jacobsen Mey, a Dutch explorer who was working for the Dutch East India Company.

The city of Cape May is located on the island (south of the peninsula) and home of the oldest seaside resort in America, with historical roots dating back to the 18th century. The entire city was designated as a National Historic Landmark on May 11, 1976, and many of the buildings throughout the town are original Victorian structures that have been maintained in pristine condition.

The peninsula comprises the municipalities of Middle Township, Avalon, Dennis Township, Stone Harbor, North Wildwood, West Wildwood, Wildwood, Lower Township, Wildwood Crest, North Cape May, West Cape May, Cape May, and Cape May Point. The region is a popular destination for Québécois tourists. It is part of the Southern Shore Region.

Cape May is also famous as one of the top birding sites in North America. There are many different parks and birding sites in the area. Due to its location at the southern tip of New Jersey and numerous nature preserves and wildlife refuges, large concentrations of birds can be found in Cape May, especially during spring and fall migration. The Cape May Bird Observatory acts as the central coordinator of birding activities in Cape May, including the World Series of Birding, held in Cape May (and throughout New Jersey) each May.

The basic training camp of the United States Coast Guard is located in Cape May. This facility is the only enlisted basic training center for the United States Coast Guard in the country. Each recruit goes through eight weeks of training before they are shipped out to various locations.
