A liquid discharge head includes discharge orifices, recording elements that generate energy, supply channels that supply liquid to the recording elements, a common supply channel communicating with the supply channels, recovery channels that recover liquid supplied to the recording elements, a common recovery channel that recovers liquid from the recovery channels, a first inlet port that supplies liquid to the common supply channel, a first recovery port that recovers liquid from the first common supply channel, a second inlet port that supplies liquid to the common recovery channel, and a second recovery port that recovers liquid from the second common recovery channel. The first inlet port and the first recovery port communicate without going through channel portions where recording elements are disposed, and the second inlet port and the second recovery port communicate without going through channel portions where recording elements are disposed.
