The River Aire is a major river in Yorkshire, England, 92 miles (148 km) in length. Part of the river below Leeds is canalised, and is known as the Aire and Calder Navigation.

The Handbook for Leeds and Airedale (1890) notes that the distance from Malham to Howden is 58 miles (93 km) direct, but the river's meanderings extend that to 90 miles (140 km). Between Malham Tarn and Airmyn, the river drops 1,300 feet (400 m).
