Thomas Maltby Grindley (November 8, 1864 – October 20, 1929)[1] was a politician in Alberta, Canada and a municipal councillor in Edmonton.

He joined the military and took part in suppressing the North-West Rebellion in 1885, serving under Sam Steele.

In 1886, he left the Chipam Brothers and opened a general store in Fort Saskatchewan, where he also served as a school trustee.

In the 1904 municipal election, Grindley ran for alderman on Edmonton City Council.

However, Edmonton's merger with Strathcona necessitated an entire new Council to be elected in February 1912, and Grindley's term was truncated.
