Thomas Sullivan[1] (born November 23, 1977) is a Canadian curler from Halifax, Nova Scotia.

At the juniors, he led his team to a 7–5 round robin record, which was good enough to be in a five-way tie for third place.

They won their first game against the Yukon's Wyatt Redlin, but lost their second match against Ontario, skipped by future Olympic gold medalist John Morris.

Sullivan won one World Curling Tour event with Dacey, the 2012 Challenge Chateau Cartier de Gatineau.

They also played in one Grand Slam event, the 2014 National, with Sullivan throwing lead rocks.
