Ryde, town (parish) on the northeastern coast of the Isle of Wight, historic county of Hampshire, southern England. It lies opposite Portsmouth on the mainland.
The town is located on the site of a former village called La Rye, which the French destroyed early in the 14th century. Still a small fishing hamlet by 1800, Ryde grew rapidly in the railway age as an attractive holiday resort (being incorporated in 1868). It is linked with the mainland by ferry service. Pop. (2001) 22,508; (2011) 23,999.
