The Runaway and Homeless Youth Act (RHYA, originally the Runaway Youth Act) is a US law originally passed in 1974 as Title III of the Juvenile Justice and Delinquency Prevention Act. The bill sets the federal definition of homeless youth, and forms the basis for the Runaway and Homeless Youth Program, administered by the Family and Youth Services Bureau. It has been reauthorized multiple times, and is due for re-authorization as of March 2018.
