Northwick Marina is a small marina located in Worcester, accessed directly from the River Severn. It serves as the base for Portharb Narrowboat Holidays and also offers private moorings.

In September 2009, Worcester City Council approved a £500,000 redevelopment of the site, which included enlarging the basin, constructing a new footbridge across the access channel, and upgrading other facilities, with the majority of work planned for 2010.
