The Royal Lincolnshire Regiment was a line infantry regiment of the British Army raised on 20 June 1685 as the Earl of Bath's Regiment for its first Colonel, John Granville, 1st Earl of Bath. In 1751, it was numbered like most other Army regiments and named the 10th (North Lincoln) Regiment of Foot. After the Childers Reforms of 1881, it became the Lincolnshire Regiment after the county where it had been recruiting since 1781.
