The Yorktown-class was a class of three steel-hulled, twin-screw gunboats built for the United States Navy beginning in 1887. All three ships of the class were named after cities near American Revolutionary War battles.

The ships were just over 244 feet (74 m) long and 36 feet (11 m) abeam and displaced a little more than 1,700 long tons (1,730 t). They were equipped with two steam engines which were supplemented with three schooner-rigged masts. The main battery of each ship consisted of six 6-inch (15.2 cm) guns and was augmented by an assortment of smaller caliber guns.

Ships of the class were in commission between 1889 and 1919. For most of their service, the ships were in the Pacific, patrolling the coasts of North and South America, Hawaii, and the western Pacific. Yorktown-class ships saw service in many of the conflicts involving the United States from the 1890s through World War I, with all three ships seeing action during the Philippine–American War. Yorktown was involved in the 1891 Baltimore Crisis in Chile, participated in the China Relief Expedition carried out in the wake of the Boxer Rebellion, and served as a convoy escort in World War I. Concord was a part of Admiral George Dewey's fleet at the Battle of Manila Bay during the Spanish–American War.
