Model Arts and Niland Gallery, Contemporary art museum and arts centre in Sligo, Ireland.

The Model, home of the Niland Collection, occupies a two-storey Italianate Palazzo-style building of rubble and ashlar stone on the Mall, north of the Garavogue river in Sligo. Architect James Owen designed it for the Board of Works. Inside are gallery spaces on a complete circuit, a purpose-built performance space and cinema, a bookstore, a cafe and eight artist studios.

The building was constructed in 1862 as a Model School and displays Italian Palazzo style, designed by architect James Owen. It was converted into an arts centre in 2001.

The Niland Collection displays over 300 works by Irish artists and houses significant paintings by Jack Butler Yeats, Paul Henry, and Louis le Brocquy. These works form the core of the venue and draw art lovers from across the region.

The Model sits on the Mall, north of the Garavogue river, with its main entrance added on the north side during the 2008–2010 redevelopment. The building has a complete gallery circuit, a reception area, bookstore and cafe, plus a purpose-built performance space and eight artist studios. Film screenings are presented with Sligo Film Society.

The 2008–2010 extension was designed by Sheridan Woods Architects and added artist studios, a purpose-built performance space and a new north entrance. It was part of a planned Sligo Cultural Quarter beside a new county museum and town library; the economic crisis stopped those two neighbours, but the Model's extension went ahead and reopened on 1 May 2010.
