Grolley-Ponthaux (French: [ɡʁɔlɛ pɔ̃to]) is a municipality in the district of Sarine in the canton of Fribourg in Switzerland.

[1] Grolley-Ponthaux is located between Fribourg in the east and Payerne in the west, on the divide between the Broye and Sarine watersheds.

[2][4] A vehicle park for the Swiss Army and a wastewater treatment plant were built in Grolley in 1970, and a new primary school in 1972.

While Ponthaux has retained its agricultural character,[4] Grolley has experienced some residential development since the 1980s due to its proximity to Fribourg,[3][10] and it has an industrial park.

[11] Grolley-Ponthaux is located on Swiss main road H157, which connects it to Fribourg in the east and Payerne in the west.
