John Elkington Gill was a 19th-century architect in Bath, Somerset, England. He was partnered with the more famous George Phillips Manners, and continued the latter's practice upon Manner's retirement in 1862. Upon Manner's death in 1866, he changed the name of the practice to his name alone. He set up the practice of Gill & Browne in 1874 before he died but he was then mostly retired and the work of Gill & Brown is almost entirely the work of Thomas Browne alone.
John Elkington Gill's son was Wallace Gill, who in 1879 had his name added to the practice and in 1899 renamed the practice Gill and Morris. Wallace Gill went by his own name from 1903 and retired in 1909, transferring the practice to Mowbray A. Green.
