Abstract: A collapsible hat support device adapted to support a hat having a crown and brim on a support surface. The support device comprises a base adapted for stable support on a substantially flat support surface and a continuous, elongated hat support arm pivotally connected to the base. The support arm is movable between a lowered storage position adjacent the base and a raised hat support position. The support arm is adapted to be received within and engage the interior portion of the hat crown for support of the hat with the brim in spaced relation from the support surface. A means for releasably securing the hat support arm in at least the raised hat support position is included. This securement means may be flexible wire connectors used to connect the arm to the base. At least one hook support member is operatively connected to the base for supporting the base from a nail, door top or other horizontal surface and against an upright surface.
