Jardin de l'Hôtel-Lamoignon - Mark-Ashton, Public garden in Le Marais, Paris, France.

The Jardin de l'Hôtel-Lamoignon - Mark-Ashton is a public garden at 25 rue des Francs-Bourgeois, beside the Hôtel de Lamoignon. A central lawn enclosed by a low fence of short dark posts linked by thin wire is flanked by curving gravel paths; the near path runs above a low curved concrete retaining wall over a cobbled surface of rectangular setts. A raised stone retaining wall topped with red and yellow flowers, wooden benches and stone steps to a higher level complete the layout.

The park was created in 1969 as an extension of the Historical Library of Paris on land where the Hôtel d'Angoulême Lamoignon once stood. This space thus emerged from a significant historical property in the Marais.

On 25 September 2018 the Council of Paris named the garden after Mark Ashton (1960–1987), founder of Lesbians and Gays Support the Miners. It was inaugurated on 1 December 2018, World AIDS Day, and serves as a memorial to people who have died from AIDS.

The garden is reached at 25 rue des Francs-Bourgeois, either from the street or through the Hôtel de Lamoignon, which houses the Bibliothèque historique de la Ville de Paris. The nearest metro is Saint-Paul on line 1. Inside, gravel paths curve around a central lawn behind a low fence, with stone steps on one side leading to a higher level.

The garden was officially named and inaugurated on 1 December 2018, during Paris events for World AIDS Day, after the Paris Council voted on 25 September 2018 to honour Mark Ashton (1960–1987), founder of Lesbians and Gays Support the Miners. The space opened to the public in 1969 as a dependency of the Bibliothèque historique de la ville de Paris.
