A foldable chair frame includes cross-shaped front and rear leg units, and first and second side frame units. Each of the side frame units includes first, second and third side leg members, and a coupling member. The first side leg member has two ends respectively connected to a lower front leg part of one of the front leg units and an upper rear leg part of one of the rear leg units, and an intermediate leg portion pivotally connected to the coupling member. The second side leg member has two ends respectively connected to an upper front leg part of one of the front leg units and a front end section of the coupling member. The third side leg member has two ends respectively connected to a lower rear leg part of one of the rear leg units and a rear end section of the coupling member. One of the second and third side leg members is connected pivotally to the coupling member to permit movement of the second and third side leg members away from the first side leg member to an unfolded position. The coupling member is provided with first and second limit units to arrest movement of the second and third side leg members relative to the first side leg member when the chair frame is folded.
