The Doll Asylum is an annual Halloween experience and makeshift doll-themed museum, originally hosted at a couple's private residence in Portland, Oregon's Piedmont neighborhood, in the United States.

Mark Williams and Heidi Loutzenhiser originally decided to host an open house as a way to meet their new neighbors, having moved to the neighborhood in 2010.
