The Dorset Regiment was an infantry regiment of the British Army.

It was formed in 1881 by the amalgamation of

• the 39th Regiment of Foot - the 39th (Dorsetshire) Regiment
• the 54th Regiment of Foot - the 54th (West Norfolk) Regiment

Until 1951 it was formally called The Dorsetshire Regiment, although usually known as "the Dorsets".

In 1958 it amalgamated with the Devonshire Regiment to form the Devonshire and Dorset Regiment.
