The Hydrographer of the Navy is the principal hydrographical Royal Naval appointment. From 1795 until 2001, the post was responsible for the production of charts for the Royal Navy, and around this post grew the United Kingdom Hydrographic Office (UKHO).

In 2001, the post was disassociated from UKHO, and the Hydrographer of the Navy is now a title bestowed upon the current captain—hydrography and meteorology—on the staff of the Devonport Flotilla at HMNB Devonport.
