Gilbert William Bayes (4 April 1872 – 10 July 1953) was an English sculptor.
Bayes was born in London into a family of artists, his father being Alfred Walter Bayes, an established artist at the time. He was one of four children and brother to the well-known artist and critic Walter Bayes, and to the Arts & Crafts designer Jessie Bayes. Bayes' lengthy and illustrious career began as a student under Sir George Frampton and Harry Bates, and so became associated with the British New Sculpture movement and its focus on architectural sculpture.
Bayes is perhaps best remembered for his interest in color, his association with the Royal Doulton Company, and his work in polychrome ceramics and enamelled bronze. His major ceramic frieze at the Doulton Headquarters of 1938 was removed in the 1960s when the building was razed, and re-located to the gallery at the Victoria and Albert Museum which bears his name. He also designed a number of war memorials, with public works throughout the former British Empire, from New South Wales to Bangalore.
Bayes served as President of the Royal British Society of Sculptors, PRBS, from 1939 through 1944. He died in London in 1953. Bayes' home at 4 Greville Place in St. John's Wood bears a blue plaque placed by English Heritage in 2007.
In 1906, Bayes married Gertrude Smith, a fellow sculptor, in Farnham, Surrey. They had two children:
