Lanark County is a county and census division located in the Canadian province of Ontario. Its county seat is Perth, which was first settled in 1816 and was known as a social and political capital before being overshadowed by a city known today as Ottawa.
Most European settlements of the county began in 1816, when Drummond, Beckwith and Bathurst townships were named and initially surveyed. The first farm north of the Rideau was cleared and settled somewhat earlier, in 1790. The county took its name from the town of Lanark in Scotland. Nearly all the townships were named after British public and military figures from the era of early settlement.
