Oegstgeest (Dutch pronunciation: [ˌuxstˈxeːst] ⓘ) is a town and municipality in the province of South Holland in the western Netherlands.

The name was formerly often spelled Oestgeest or Oostgeest, which could indicate the geographical location of the village: east of the geest lands.

However, the oldest spelling found in a copy of a list of goods of the St. Martin's Cathedral in Utrecht from the tenth century states Osgeresgeest.

In 1399, the heerlijkheid of Oegstgeest and that of Poelgeest were merged because their declining populations could no longer afford to pay the required taxes to the Count of Holland.

First Wilhelminapark was built, followed by Prins Hendrikpark (circa 1915), Buitenlust or Indische Buurt (1925), Julianapark, Oranjepark, and Emmapark (1920-1950), and Grunerie and the area between Emmalaan and Lange Voort (1950s).

At LOHC hockey is played and the neighbouring OLTC (founded 1886) is the tennis club of the municipality.
