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.

[2] The next year, Sullivan won his one and only provincial championship, playing third for the Terry Odishaw rink.

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