Tucked into the scenic Qu’Appelle Valley along the banks of the Qu’Appelle River, Tantallon sits within the Rural Municipality of Spy Hill No. 152, part of Census Division No. 5 in eastern Saskatchewan. The village lies roughly 39 km east of Round Lake, placing it in a region defined by the gentle contours of the valley. Students from the community are bused to Esterhazy for their schooling, following the closure of the local school due to declining enrolment.
Tantallon was formally incorporated as a village on June 17, 1904, and marked its centennial in 2004. Its name traces back to a homestead established by Scottish Canadian James Moffat Douglas, a former Canadian MP and Senator, who felt the surrounding Qu’Appelle Valley landscape bore a resemblance to Tantallon Castle in Scotland. The community recorded a population of 84 residents in the 2021 federal census, spread across 48 of its 51 private dwellings, representing a decline of roughly 7.7% from the 91 residents counted in 2016. That 2016 figure itself marked a 15.4% drop from the 105 people recorded in 2011. The village covers a land area of 0.84 km², with a population density of approximately 100 people per km² as of 2021. Local amenities include an ice rink and a seniors centre.
