Armstrong is a compact rural community, unincorporated place, and divisional point on the Canadian National Railway transcontinental railway main line in the unorganized portion of Thunder Bay District in Northwestern Ontario, Canada.

The Armstrong area is a popular tourist destination in the summer for fishing and hunting.

The community is not part of an incorporated municipality, but is administered by a local services board.

Later that year the base was sold to private owners and turned into a popular gathering area for the town that included a restaurant and bar, hotel, multiple apartments, garages, and a curling rink.

The town of Armstrong currently has a public school, two restaurants, a Canada Post post office, a clinic, a Mini Mart gas station and motel, and the Armstrong General store (formally J&J General store 1961–2015).
