Happy Valley Tea Estate is a tea garden in Darjeeling district of West Bengal established in 1854; it is Darjeeling's second oldest tea estate. Spread over 177 hectares, it is situated at a height of 6,900 ft above sea level, 3 kilometers north of Darjeeling. This tea estate is the closest to Darjeeling town, and which would offer trips around the factory and tea tasting.

The months of April to June are the busiest time here when plucking and processing are in progress and employs more than 1500 people. David Wilson named the garden Wilson Tea Estate and had started cultivation of tea by 1860. In 1903, the estate was taken over by an Indian, Tarapada Banerjee, an aristocrat from Hooghly. In 1929, Banerjee bought the Windsor Tea Estate nearby and merged the two estates under the name of Happy Valley Tea Estate.

He established a new factory within the premises, and started the modernisation process, replanting and switching to organic farming. Finally, the estate reopened to the public in 2008, with the original factory turned into a working museum. It also displayed single-piston, slow-speed engines, and the shaft machines and sells tea-related mementos.
