Manuel Quimper del Pino was a Spanish explorer of French paternity who participated in exploration and settlement expeditions for Spain along the Pacific Coast of North America. He is best known for charting the Strait of Juan de Fuca and the San Juan Islands in the late 18th century. His missions sailed from the Spanish naval port at San Blas on the Pacific coast of New Spain, which was established by Spain in the 1760s to support the exploration and settlement of the Pacific Coast of North America.

In 1789 Quimper was a sub-lieutenant on an expedition under Spanish Captain Estaban José Martinez and Lieutenants Francisco Eliza and Salvador Fidalgo to explore the Strait of Juan de Fuca, which had been sighted by Capt. Martinez in 1774. Quimper was assigned the task of establishing a settlement at Nootka Sound.

Another Spanish expedition sailed north from San Blas in early 1790 under Captain Francisco Eliza to strengthen the settlement at Nootka Sound and to further chart the waters of the Strait of Juan de Fuca and the San Juan Islands. Spanish names were assigned to many geological features which were later renamed by British Captain George Vancouver in 1792. Features which retained their Spanish names include Rosario Strait and Fidalgo Island.
