Early on, the area that is now Seal Beach was known as "Anaheim Landing", as the boat landing and seaside recreation area named after the nearby town of Anaheim.
By the 20th century, it was known as Bay City, but there was already a Bay City located in Northern California. When the time came to incorporate on 25 October 1915, the town was named Seal Beach. The town became a popular recreation destination in the area, and featured a beach-side amusement park long before Disneyland was founded inland.
The United States Navy's Naval Weapons Station Seal Beach was originally developed during World War II for loading, unloading, and storing of ammunition for the Pacific Fleet, and especially those US Navy warships home-ported in Long Beach. With closure of the Long Beach Naval Shipyard, the Weapons Station has become more involved in the research and development of missiles, torpedoes and conventional ammunition.

The Seal Beach National Wildlife Refuge is located on part of the Naval Weapons Station Seal Beach. Much of the refuge's is the remnant of the saltwater marsh in the Anaheim Bay estuary (the rest of the marsh became the bayside community of Huntington Harbour, which is part of Huntington Beach). Three endangered species, the light-footed Clapper Rail, the California Least Tern, and the Belding's Savannah Sparrow, can be found nesting in the refuge. With the loss and degradation of coastal wetlands in California, the remaining habitat, including the Bolsa Chica Ecological Reserve in Huntington Beach and Upper Newport Bay in Newport Beach, has become much more important for migrating and wintering shorebirds, waterfowl, and seabirds. Although the refuge is a great place for birdwatching, because it is part of the weapons station, access is limited and usually restricted to once-a-month tours.
The second longest wooden pier in California (the longest is in Oceanside) is located in Seal Beach and is used for fishing and sightseeing. There is also a restaurant (Ruby's) at the end of the pier. The pier has periodically suffered severe damage due to storms and other mishaps, requiring extensive reconstruction. A plaque at the pier's entrance memorializes Federal Emergency Administration of Public Works, 1938, Project No. Calif. , a rebuilding necessitated by storms in 1935. Another plaque honors the individuals, businesses, and groups who helped rebuild the pier after a storm on March 2, 1983, tore away several sections. Most prominent was a "Save the Pier" group formed in response to an initial vote by the City Council not to repair the pier. The ensuing outcry of dismay among residents caused the City Council to reverse its stance while claiming the city lacked the necessary funds. Residents mobilized and eventually raised $2.3 million from private and public donors to rebuild the pier.
