Nicolas Lebrun (born 1985 in Carpentras, France) is a visual artist based in Montpellier. He graduated from the École supérieure des Beaux-Arts de Montpellier (DNSEP, 2011).

From 2009 to 2015, he created interactive installations that questioned the materiality of the artwork and the role of the viewer (62.161.153.125, Reflection). Even then, each work grew out of a framework set in advance, in the wake of François Morellet. That principle then took over. His practice turned to systematic series based on strict protocols, in digital, physical or hybrid forms. One example is Ecluse, in which every generated edition is hand-painted.

Each project is a system: an initial state, then a transformation that fixes the composition. The grid is often the starting point, before being fragmented or distorted (Degenerative Grid, Variationes circa triangula).

These systems question our relationship to reality. Through plays of perspective, nested planes and the spatial distribution of elements, they put our perception of space to the test (Vanishing Points, Grid on Grid, Carceri d’invenzione). They also examine representations and what they tell us about reality and knowledge. In Degenerative Architecture, the program alters photographed façades until it replaces them with its own images. In Chat, archives of thinkers are replayed in an instant messaging interface. Language is no exception: projected onto volumes or repeated like a line of code, text becomes a form subject to the protocol (Ourobouros, Barrage).

His work has been shown at the Villa Arson (2010), the CRAC in Sète (2012), the Salon de Montrouge (2014) and MO.CO. (SOL! Biennial, 2026), and at the Lacuna (2022) and SIMULTAN (2025) festivals.
