Wasaga Beach Provincial Park

Wasaga Beach Provincial Park is a provincial park located on Georgian Bay at Wasaga Beach, Ontario, Canada. The beach (with the exception of a short separate area of private beaches in the extreme west end) is owned and operated by Ontario Parks as a recreational provincial park, consisting of the town's trademark beach, as well as other non-beach areas. Beach Areas 1–6 can be accessed off Mosley Street, while Allenwood and New Wasaga Beaches are northeast of the mouth of the Nottawasaga River and are accessed via River Road East.

The park is available for day use only. Its area totals 1,844 hectares (4,560 acres) of which 6.8 hectares (17 acres) are protected. The park is a habitat for birds, primarily for shorebirds including the endangered piping plover. In addition to the beach, there are over 50 kilometres (31 mi) of hiking trails. In winter, they are used for cross-country skiing and snowshoeing. The visitor centre provides access to the Nancy Island Historic Site with a theatre, a museum and a lighthouse.

It had 1,693,731 visitors in 2022, making it the most-visited operating provincial park in Ontario.
