Jardin botanique Nicolas Boulay, Botanical garden at Catholic University of Lille, France.

The Jardin botanique Nicolas Boulay is a botanical garden on the grounds of Catholic University of Lille featuring plant collections organized into themed sections. The space is structured around the university's research and educational needs, with displays arranged to support both student training and scientific study.

The garden bears the name of Abbé Jean-Nicolas Boulay (1837–1905), who founded it and held the chair of botany at the Faculté Libre des Sciences, also teaching at the Faculty of Medicine. He spent the last three decades of his life on botany and natural sciences, studying plant geography, the taxonomy of Rubus and mosses, and fossil plants.

The garden is named after botanist Abbé Jean-Nicolas Boulay and serves as a working space for the university's Faculty of Medicine and students. Today, the plant collections reflect the scientific focus that has defined this place since its creation.

The garden is accessible through the Catholic University of Lille campus, with an interactive map to help visitors navigate the different plant sections. Plan to spend time walking through the themed areas to see the full range of collections on display.

Boulay spent the last three decades of his life teaching botany and researching phytogeography, the taxonomy of the genus Rubus, mosses and fossil plants. He also founded the basis of an anthropological museum, alongside this garden.
