The Royal Brunswick Ground, also known as "C H Gausden's Ground", in Hove, Sussex was a venue for first-class cricket matches from 1848 to 1871. The ground was situated to the west of the Brunswick Town area of Hove, roughly where Third and Fourth Avenues are today. As the land near the seafront was required for the expansion of the town, the club moved in 1872. 
The ground was the home of Sussex County Cricket Club which had previously (1814–1847) been based at the Royal New Ground. In all, 64 first-class matches were played at the Royal Brunswick. The ground was used for many non-Sussex county matches, for example in 1864, a "Gentleman of Sussex" team played against a "Gentleman of South Wales" team, in 1866, county players played a match against a team including nine "Gentleman of the County" and nine "Colts of Sussex", and in 1866 the ground was used for a match between Brighton Club and Eashing Park Club. Since 1872, the club has been based at the County Cricket Ground, Hove, its present home.
