Crabtree is celebrated in one of the Manchester Murals in the Great Hall of Manchester Town Hall, where a romanticised depiction of his recording of the transit can be seen (pictured) entitled Crabtree watching the transit of Venus AD 1639 painted by the artist Ford Madox Brown in 1881.

On 9 June 2004, the day after a transit occurred as predicted by Horrocks, a commemorative street nameplate in memory of William Crabtree was unveiled at the junction of Lower Broughton Road and Priory Grove which marks the northern boundary of Crabtree Croft.
A commemorative plaque was unveiled a few yards away in December 2005, at Ivy Cottage 388-90 Lower Broughton Road, which is thought most likely to have been the home of Crabtree and his family at the time when he was collaborating with Horrocks.

The second transit of the pair occurred on 5 and 6 June 2012 and a celebration was held at Ivy cottage, when NASA broadcast a recreation of the observation, inspired by the Ford Madox Brown mural, to millions of viewers and projected a live stream of the transit from Hawaii on the side of the house.

Minor planet 4137 Crabtree is named after him.
