Parc Michel-Chartrand, Urban park in Le Vieux-Longueuil, Canada.

Parc Michel-Chartrand is a 1,850,000-square-metre park at 1895 Rue Adoncour in the Le Vieux-Longueuil borough of Longueuil, Quebec, comparable in area to Mount Royal Park. Its grounds hold a marsh, three artificial lakes, a sundial, a playground, two pétanque courts, picnic tables, a sledding slope, an ice rink and community gardens.

The site was established in 1975 as Base de plein air de Longueuil and received its current name in 2010 to honor Quebec labor activist Michel Chartrand. This renaming recognized a figure who fought for workers' rights in the region.

The park is named after Michel Chartrand, a Quebec union activist, following the city's June 2010 decision to rename it. Since 2016 it has held La force ouvrière, a monumental sculpture also honouring Chartrand, which visitors can see on the grounds. The site was first opened in 1975 as the Base de plein air de Longueuil.

In winter, visitors can travel on about 12.5 kilometers of cross-country skiing paths, while warmer months offer around 10 kilometers of hiking trails. Different seasons provide varying options for outdoor activities along the available routes.

The park maintains several community gardens where local residents grow vegetables and flowers in designated plots. These gardens show resident involvement in local food growing and community life.
