Lisbon is a village in Waukesha County, Wisconsin, United States. The population was 10,477 at the 2020 census. The unincorporated communities of Colgate and Lake Five are located partially in the village.

The first settler in what became the town of Lisbon was Thomas S. Redford, who claimed 160 acres in the area in 1836. The town of Lisbon was created by the legislature of the Wisconsin Territory in 1838, ten years before Wisconsin achieved statehood. The boundaries originally included what are now Pewaukee, Brookfield, and Menomonee Falls before those three were also granted town status in 1839. The town government of Lisbon first met on April 15, 1842, in the future Lisbon Plank Schoolhouse.

The village of Sussex was founded in the middle of the town in 1924, and over time annexed pieces of the town of Lisbon. The town's economy relied on farms and stone quarries for much of its history. Lannon stone, a glacial dolomitic limestone, continues to be mined in the town along with gravel deposits.

Lisbon sought incorporation in 2011 and 2020 before the state approved the town's efforts to proceed with a referendum, which was held in January 2023. Residents approved incorporation as a village, which was certified by the state in February 2023.

According to the United States Census Bureau, the town has a total area of 29.81 square miles (77.2 km), of which, 29.81 square miles (77.2 km) of it is land and none of which is water.
