Jesmond Dene is a public park in the east end of Newcastle-upon-Tyne. It is a narrow steep sided valley through which flows a watercourse known as the Ouse Burn, the word "dene" meaning a valley in the Northumbrian dialect.

The park was first laid out by William George Armstrong and his wife during the 1860s. The design is intended to reflect a rural setting, with woodland, crags, waterfalls and pools. It is now owned by Newcastle City Council .
