Langan v. St. Vincent's Hospital is a 2005 decision of the New York Supreme Court, Appellate Division, Second Department, which held that a same-sex partner married in a Vermont civil union was not a "surviving spouse" under New York's wrongful death statute and that limiting the statute to heterosexual marriages did not violate the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution or the analogous provision in the New York Constitution.
