A folding crutch chair includes a pivot base unit and at least three support leg units. The pivot base unit has at least three mounting slots angularly spaced apart from one another about an axial line, and at least three pairs of joint portions respectively formed in the mounting slots. Each support leg unit includes a pivot seat, an outer tubular piece, and an inner tubular piece extending telescopically relative to the outer tubular piece. The pivot seat has a pair of pivot portions respectively and pivotably connected with the joint portions such that each support leg unit is rotatable relative to the pivot base unit. The support leg units are shiftable between a folded state and an unfolded state. The length of the support leg units is reduced when folded so as to facilitate packaging, storage and carrying.
