Thrapston is close to the River Nene and is at the junction of the A14 and the A45. Until the 1960s, Thrapston had two railway stations.

Thrapston (Bridge Street) was on the former LNWR Northampton to Peterborough line.
The market charter was granted over 800 years ago, in the year 1205, in exchange for two palfreys. This is celebrated every year with the town's Charter fair, where the high street is closed and the people in the town get together to commemorate this event. A relative of George Washington, Sir John Washington, lived in Chancery Lane in the town, and his wife is buried in the church. Sir John was brother to George Washington's great-grandfather. Naturalist and writer Horace William Wheelwright practiced as an attorney in Thrapston in the 1840s. Fashion photographer James Kenny currently lives in the town.
