Thomas Woolner was an English sculptor and poet who was one of the founder-members of the Pre-Raphaelite Brotherhood. He was the only sculptor among the original members.

The Pre-Raphaelite Brotherhood was a group of English painters, poets, and art critics, founded in 1848 by William Holman Hunt, John Everett Millais, Dante Gabriel Rossetti, William Michael Rossetti, James Collinson, Frederic George Stephens and Thomas Woolner who formed a seven-member "Brotherhood" partly modelled on the Nazarene movement. The Brotherhood was only ever a loose association and their principles were shared by other artists of the time, including Ford Madox Brown, Arthur Hughes and Marie Spartali Stillman. Later followers of the principles of the Brotherhood included Edward Burne-Jones, William Morris and John William Waterhouse.
