Disclosed is a portable bed sheet. The portable bed sheet comprises: a lower sheet; an upper sheet which is overlaid on the lower sheet and sewn onto the lower sheet at the left and right and bottom edges so as to form a sleeping space in between and form an opening part to the sleeping space at the top; a pillow-securing means which is disposed below the under-surface towards the top of the lower sheet and is for securing a pillow; and a quilt-securing means which is disposed on the upper surface towards the top of the upper sheet and is for securing the top end part of a quilt. In this way, a hygienic and psychologically restful sleeping environment can be created for travellers since items such as quilts and mattresses and pillows provided by businesses offering accommodation can simply be used covered by the portable bed set.
