Clane (/ˈkleɪn/; Irish: Claonadh) is a town in County Kildare, Ireland, 35.4 km (22 mi) from Dublin. With a population of 8,152 in 2022, it is the ninth largest town in Kildare and the 66th largest in Ireland. The town is on the River Liffey. Clane gives its name to the associated townland, civil parish, electoral division and surrounding barony.

Clane is located on the crossroads of the R403 and R407 regional roads.

The town most probably owes its origin to the foundation of Clane Friary in the sixth century, from about 520 A.D., when Ailbe of Emly, Bishop of Ferns, founded an Abbey in Clane and made St. Senchel the Elder its first Abbot. Saint Ultan Tua, who used to put a stone into his mouth to prevent him from speaking during Lent, and his brother Fotharnaise, are said to have been buried in Clane. They were brothers of Maighend, Abbot of Kilmainham, from whom the parish and church of Mainham, near Clane, were probably called. King Mesgegra's Mound claims links to the legendary first-century AD king Mesgegra of Leinster and was later used by Normans.

The ruins of the Franciscan monastery founded at Clane by Sir Gerald FitzMaurice, 3rd Lord Ophaly, in 1272 still exist. In 1542, Henry VIII's Commissioner granted the site and precincts of this House of Friars, manor or preaching-house of the preaching Friars of Clane to Robert Eustace, Roger Roche and Ed. Brown for £177. Besides about 70 acres (28 ha) of land in the neighbourhood – its possessions consisted of a church, cemetery, chapter-house, dormitory, store, kitchen, two chambers, stable and orchard. The dormitory and other buildings probably stood on the north side of the Abbey Church, and have long since completely disappeared.

The parish of Clane has the distinction of being the place where the rebellion of 1798 broke out; a battle between the United Irishmen and the Yeomen forces led by Richard Griffith took place on Coiseanna Hill by the modern Woods Centre. The rebels were easily defeated, and the survivors fled to Timahoe with the rest of the North Kildare rebels.

Clane has two Liffey tributaries, the Butter Stream at the south west, with a small park, and the Gollymochy River at the eastern side.

Sections of The Pale remain as ditches and hedgerows in private fields to the north of Clane.

Clane Friary and Abbey Cemetery lie to the south of the village. The Abbey, on Main Street, was formerly a church, then a ruin, and has since been restored into a community centre and garden of remembrance. The Wogan Mausoleum and churchyard lies at Mainham.

The Liffeyside Nature Park is a small wilderness area leading to a paved path by the River Liffey.
