Josselyn Van Tyne (11 May 1902, Philadelphia – 30 January 1957, Ann Arbor) was an American ornithologist and museum curator of birds.
He became Assistant Curator of Birds at the U. of Michigan's Museum of Zoology and in 1931 Curator of Birds, a position he held until his death; his successor as the museum's Curator of Birds was Harrison B. Tordoff.
Most of his time was spent inside his office and the museum, but every year he aimed to get out at least once on an extended field trip.
Over the years his travels carried him to Indo-China (the Kelley-Roosevelt expedition of 1928–1929), the Panama Canal Zone, Guatemala, British Honduras, Yucatan, the Bahamas, Canadian Arctic, Europe, the Chisos Mountains of Texas, and nearly every part of Michigan.
He was a productive collector, and thousands of near-perfect bird skins, many of them preserved under difficult tropical conditions, give evidence of his skill as a preparator.
