Parc Théodore-Monod, Public garden in Le Mans, France.

Parc Théodore-Monod is a 2-hectare botanical garden with diverse plantings and water features. It includes four basins with water lilies, stone waterfalls, and winding pathways connecting different garden zones.

The site once held the Chanzy military barracks, built between 1875 and 1878 and used to house infantry regiments until the 1990s. The barracks were then transformed into this public garden space.

The park is named after Théodore Monod, the naturalist who died in 2000, the year before work began. Two entrance pavilions of the former Chanzy barracks were kept and turned into toilets, a keeper's office and an exhibition room. One barrack block along rue Marceau became some thirty flats and a crèche.

The garden is open daily starting at 9 AM with seasonal closing times varying by season. Visitors will find children's play areas, restroom facilities, and shaded spots throughout for comfort.

The park was laid out on the site of the Chanzy barracks, built between 1875 and 1878 for the 117th Infantry Regiment. The city kept one barrack block along rue Marceau, decided by the municipal council under Robert Jarry on 16 October 1998, and two entrance pavilions, now toilets, a keeper's office and an exhibition room. A plaque about the 117th RI is planned at the entrance.
