The invention discloses a seat backward locking device and a child seat, and relates to the field of seats. The seat backward locking device comprises an annular groove, a check block, a pair of locking buttons, a pair of limiting blocks and an unlocking button, wherein the annular groove and the check block are arranged on the base and the seat body respectively, the locking buttons move between the first station and the second station, the limiting blocks are connected to the two locking buttons respectively, and the unlocking button moves between the third station and the fourth station. The seat body drives the stop block to move along the annular groove when rotating relative to the base; when the locking button moves, the limiting blocks are driven to be separated from or stretch into the annular grooves. When the unlocking button is located at the third station, the two locking buttons located at the first station or the second station are locked, and when the unlocking button is located at the fourth station, the two locking buttons are unlocked; and when the two limiting blocks respectively extend into the annular grooves, the seat body facing the back of the base is limited to only rotate by 90 degrees clockwise and anticlockwise. According to the seat backward locking device and the child seat, the seat can be limited to rotate from the position towards the rear of the base to the position towards the front of the base, and therefore a user can be better protected.
