Harrogate ( HARR-ə-gət, -⁠gayt, -⁠ghit) is a spa town in the district and county of North Yorkshire, England. Historically in the West Riding of Yorkshire, the town is a tourist destination and its visitor attractions include its spa waters and RHS Harlow Carr gardens. 13 miles (21 km) away from the town centre is the Yorkshire Dales National Park and the Nidderdale AONB. Harrogate grew out of two smaller settlements, High Harrogate and Low Harrogate, in the 17th century. For three consecutive years (2013–2015), polls voted the town as "the happiest place to live" in Britain.

Harrogate spa water contains iron, sulphur and common salt. The town became known as 'The English Spa' in the Georgian era, after its waters were discovered in the 16th century. In the 17th and 18th centuries its 'chalybeate' waters (containing iron) were a popular health treatment, and the influx of wealthy but sickly visitors contributed significantly to the wealth of the town.

Harrogate railway station and Harrogate bus station in the town centre provide transport connections. Leeds Bradford Airport is 10 miles (16 km) southwest of Harrogate. The main roads through the town are the A61, connecting Harrogate to Leeds and Ripon, and the A59, connecting the town to York and Skipton. Harrogate is also connected to Wetherby and the A1(M) by the A661, while the A658 from Bradford forms a bypass around the south of the town. Harrogate had a population of 73,576 at the 2011 UK census; the built-up area comprising Harrogate and nearby Knaresborough had a population of 89,060, while the figure for the much wider Borough of Harrogate, comprising Harrogate, Knaresborough, Ripon, as well as a number of smaller settlements and a large rural area, was 157,869.

The town motto is Arx celebris fontibus, which means "a citadel famous for its springs".
