A sliding groove type friction pendulum high-pier bridge seismic mitigation and an isolation bearing. The bearing includes an upper connecting steel plate, a lower connecting steel plate, and a frictional sliding component clamped between the upper connecting steel plate and the lower connecting steel plate. The frictional sliding component includes an upper bearing plate, a lower bearing plate, and a hyperbolic spheroid. The upper bearing plate and the lower bearing plate are disposed on corresponding connecting steel plates, and are mounted and cooperate by using a plurality of parallel protrusions and grooves. The hyperbolic spheroid is disposed between the upper bearing plate and the lower bearing plate. A plurality of hysteretic damping components, bearing positioning structures, butterfly-shaped spring components, and bearing limiting structures are disposed on opposite surfaces of the upper bearing plate and the lower bearing plate in a circumferential direction.
