Tottenham is a community in the town of New Tecumseth, in south-central Ontario, Canada. It takes its name from its first postmaster, Alexander Totten. The Tottenham Conservation Area is a recreational facility in the village, which is also famous for its annual event, the Tottenham Bluegrass Festival. There is also a restored steam train that is a tourist attraction, taking passengers to Beeton and back. Tottenham is home to three schools: Tottenham Public School, Father F.X. O'Reilly School, and Saint Thomas Aquinas Catholic Secondary School.

The town was ravaged by a fire in 1895, which began at the McKinney foundry. Eighty structures were destroyed, including the foundry and a Methodist church. Despite warnings in 1884 that the town needed a fire engine, none was purchased. To combat the 1895 fire, the town of Allandale sent its fire engine, preventing further spread of the fire.
