Asa Eldridge (1809–1856) was a sea captain from Yarmouth, Massachusetts. In 1854, Captain Eldridge guided the clipper ship Red Jacket from New York and to Liverpool in only in 13 days, 1 hour, and 25 minutes, dock to dock, setting a speed record for the fastest trans-Atlantic crossing by a commercial sailing vessel that has remained unbroken ever since. In 1856, Captain Eldridge skippered the ill-fated steamship SS Pacific, which disappeared at sea on a voyage from Liverpool to New York.
