Voorhout (Dutch pronunciation: [ˈvoːrɦʌut] ⓘ) is a village and former municipality in the western Netherlands, in the province of South Holland.

Voorhout is located in an area called the "Dune and Bulb Region" (Duin- en Bollenstreek).

It also included the communities of Piet Gijzenbrug (partly) and Teijlingen with the Slot Teylingen.

The nearby Noordwijkerhout also refers to this forest, just like Holland, which is a degeneration of Holtland, meaning woodland.

In 1657 the Leidsevaart canal was dug, going from Haarlem to Leiden and Voorhout started to grow because of this.

Until World War II the main source of income in Voorhout was from the flower bulb industry.
