Boyd Conservation Area, Conservation area in Vaughan, Canada.

Boyd Conservation Area is a park in Vaughan, Ontario, owned by the Toronto and Region Conservation Authority, occupying a stretch of the Humber River valley north of Woodbridge. It holds forest, picnic grounds, a beach area on the river, and sports courts, with trails that continue north to Bindertwine Park in Kleinburg.

In 1956 the Humber Valley Conservation Authority bought land along the Humber north of Woodbridge, near the hamlet of Pine Grove, to create public recreation space and preserve valley lands for flood control after Hurricane Hazel. The park opened to the public in 1957 with forested areas, trails, picnic grounds and a beach on the Humber used for swimming.

In September and October the park hosts cross-country running, most notably the OFSAA provincial schools meet, held here in 1960–65, 1968–72, 1981, 1989 and 2009. Summer brings outdoor concerts at the sheltered sites, and businesses book one of 19 picnic sites for corporate outings.

The area offers well-marked trails suitable for walking and running through different zones of the conservation area. Visitors should wear sturdy footwear as ground conditions vary depending on the season and recent weather.

Boyd's full-time staff move to the Kortright Centre for the winter, and in summer the grounds are kept by students and community-service volunteers. Staff wear powder-blue shirts with the TRCA crest, dark blue work trousers, steel-toed boots and TRCA caps or cowboy hats. A trail follows the Humber north through Boyd North to Bindertwine Park in Kleinburg.
