Badshot Lea is a village in Surrey, England, close to Aldershot. Badshot Lea has access in either direction to the A31 and A331 and is connected to railway stations in the nearby towns with regular bus services. The village is part of the Blackwater Valley or Aldershot Urban Area, the thirtieth largest conurbation in the UK. Badshot Lea's boundaries are four bridges—three western railway bridges and Pea Bridge over the uppermost part of the River Blackwater— these inspired a logo for the village and the football team who play in the larger neighbouring village of Ash. The Blackwater separates Badshot Lea from Aldershot to the north; the eastern and western boundaries are short and the southern boundary is the A331.

In prehistory mammoths were in the area now encompassed by the village boundaries, evidenced by the Mammoth tusks occasionally excavated by Surrey Archaeological Society.

The village has remains in, or close to, the village from the Mesolithic, Neolithic, Iron Age, Roman and medieval periods. In 1967 the Badshot Lea Village school master and amateur archaeologist William (Billy) Rankine discovered the remains of a Neolithic Long Barrow (burial mound also known as a tumulus) here. The site was excavated by the Surrey Archaeological Society and many finds are on display at Guildford Museum. Little remains of the original mound due to quarrying and the excavation of the Railway cutting in the 1800s. The burial mound was sited close to the Harrow Way. The village used to be surrounded by thriving farms, with a particular focus on hop growing; these played such an important role in the economic development of the village that hops feature in the village logo.

The eastern end of the village has suffered terrible flooding. This led to the road near the Aldershot boundary being nicknamed the 'docks'.

Badshot Lea is close to the GHQ Line pill box fortifications built during World War II to defend London in the event of a successful German invasion of Britain in Operation Sea Lion. An example can still be found behind the rifle range.
