A strap holding structure (200) for an electronic device (100) includes a body (10), a strap holder (22) and a latching element (24). The body defines a receiving portion (12). The receiving porting has a side board (1242). The side board with the receiving portion cooperatively surrounds a space (1244). The strap holder has a pole (228) at one end thereof and two opposite feet (223) extending from another end thereof. A block (226) radially extends from a circumferential wall of the strap holder, and the side board is received in the space. The latching element forms two concave portions (244). Each foot engages with a corresponding concave portion. A stopper (246) perpendicularly protrudes from the latching element, and resists a wall of the receiving portion.
