The Sint-Lambertuskerk (St. Lambert's) is a former church in the city of Maastricht, Limburg, Netherlands.

At the time of its completion in 1916, St. Lambert's was the first church in Maastricht outside the medieval city wall.

The church was designed by Hubert van Groenendael in neo-Romanesque style on a cruciform plan.

The church was named after the Maastricht-born saint Lambert, bishop of Maastricht and Liège in the 7th and 8th century.

The parish moved to the nearby St. Ann's Church in the same neighbourhood of Brusselsepoort.
