Perth is a town in Eastern Ontario, Canada. It is located on the Tay River, 83 kilometres (52 mi) southwest of Ottawa, and is the seat of Lanark County. Perth is home to Canada's oldest pioneer burial ground, St. Paul's United Church Cemetery, formerly The Old Methodist Burying Ground. This cemetery is at the south-east end of the Last Duel Park on Robinson Street. The Craig Street Cemetery, sometimes referred to as the "Old Burying Grounds" also contains many historic graves and saw use from 1820–1873.

The heritage downtown core of today's Perth consists of boutiques, specialty shops and restaurants, including crafts, antiques and flea market, and summer Farmers' and Craft Markets. Most of these operate out of the century old stone buildings in town. The Perth Courier is the second-oldest weekly newspaper in Canada. The Links O'Tay Golf course, walking distance from the downtown core, began its trek through golfing history in 1890 and is now Canada's oldest continuously operating golf course.
