Abstract: A vehicle roof structure is provided capable of maintaining side collision performance of a vehicle even without a roof reinforcing member. The vehicle roof structure includes an annular frame that is joined to a circumferential edge of a roof panel (which includes an outer panel and an inner panel), and supports the roof panel. The annular frame has a higher rigidity than the roof panel, is arranged in an opening of a roof, and is joined to a pair of roof side rails, a front header, and a rear header.
