Thomas Gillow (died 1687) was an English stage actor of the Restoration era. His name was sometimes written Gilloe or Gillo. His first known role was at the Lincoln's Inn Fields Theatre in Samuel Pordage's Herod and Mariamne in 1671. He remained with the Duke's Company at the Dorset Gardens Theatre until the merger that created the United Company in 1682. His first role at Drury Lane was in John Dryden's The Duke of Guise in November that year. He remained a prominent member of the company, appearing in a mixture of comedies and tragedies. He died in May 1687 and was buried at St Bride's Church in the City of London. An actress billed as Mrs Gillow appeared at the Dorset Street Theatre between 1675 and 1678 and this may have been his wife Mary Gillow.
