A liquid discharge head includes a nozzle plate, a common chamber substrate, a channel substrate, a first bridge, and a second bridge. The nozzle plate has multiple nozzles from each of which a liquid is dischargeable in a first direction. The common chamber substrate has a supply-side common chamber having a first supply sidewall and a second supply sidewall in a second direction, and a collection-side common chamber adjacent to the supply-side common chamber in the second direction. The collection-side common chamber has a first collection sidewall and a second collection sidewall in the second direction. The channel substrate is laminated over the common chamber substrate. The first bridge is disposed between the first supply sidewall and the second supply sidewall to bridge the supply-side common chamber. The second bridge is disposed between the first collection sidewall and the second collection sidewall to bridge the collection-side common chamber.
