Alan Milliken Heisey II, KC (born c. 1954) is a Canadian lawyer who was a member of the Toronto Transit Commission Board from 2012 to 2020 and served as its vice-chair from 2015 to 2019.

He oversaw the introduction of the world's first wireless, solar-powered pay-and-display consoles that accept credit cards on Toronto streets.

[8] He was retained by the City of Toronto government to represent the environmental group 'Save the Rouge' in the Oak Ridges Moraine Ontario Municipal Board hearing in 2000–2001.

[15][16] A week after becoming chair, Heisey was the target of a smear campaign that began with the leak of an internal police memo.

Heisey refused to resign from the board, and Justice Sydney Robins of the Ontario Court of Appeal agreed that the memo was leaked to smear his name.

[25][26][27] The board unanimously endorsed Heisey's recommendations to reform the Ontario Police Complaints system in September 2004.

[42][43] In recognition of his contributions to the creation of the network, Toronto City Council ceremonially named the Sherbourne Street cycle track after him on February 10, 2015.
