The East India Squadron, or East Indies Squadron, was a squadron of American ships that existed in the nineteenth century. It focused on protecting American interests in the Far East, while the Pacific Squadron concentrated on the western coasts of the Americas and the South Pacific Ocean. Its duties included the Yangtze River Patrol in China. The East India Squadron was established in 1835 and existed until it became part of the Asiatic Squadron in 1868.

The Pacific Squadron was part of the United States Navy squadron stationed in the Pacific Ocean in the 19th and early 20th centuries. Initially with no United States ports in the Pacific, they operated out of storeships which provided naval supplies and purchased food and obtained water from local ports of call in the Hawaiian Islands and towns on the Pacific Coast. Throughout the history of the Pacific Squadron, American ships fought against several enemies. Over one-half of the United States Navy would be sent to join the Pacific Squadron during the Mexican–American War. During the American Civil War, the squadron was reduced in size when its vessels were reassigned to Atlantic duty. When the Civil War was over, the squadron was reinforced again until being disbanded just after the turn of the 20th century.
