Thomas Woolner (17 December 1825 – 7 October 1892) 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.

After participating in the foundation of the PRB, Woolner emigrated for a period to Australia. He returned to Britain to have a successful career as a sculptor, creating many important public works as well as memorials, tomb sculptures and narrative reliefs. He corresponded with many notable men of the day and also had some success as a poet and as an art dealer. One of his notable portrait medallions is that of William Wordsworth in St Oswald's Grasmere.
