Winchburgh is a town in Scotland. It is located approximately ten miles (sixteen kilometres) west of the city centre of Edinburgh, six miles (ten kilometres) east of Linlithgow and three miles (five kilometres) northeast of Broxburn.

The 2001 census recorded around 2,000 persons in Winchburgh. In 2015, the population of Winchburgh was cited as having increased to 2,430 persons. As a result of new developments (still ongoing), the 2020 population had increased by over 50% to 3,840.

Archaeological excavations in 2013 in advance of the construction of a housing development by CFA Archaeology found the remains of a sub-circular double-ditched enclosure. Not many artefacts were found and radiocarbon dates from waterlogged wood and animal bone were between 1600–200 BC, indicating the people had been living or working in Winchburgh at least a thousand years before the earliest records of the town.

There has been a settlement in Winchburgh for over one thousand years. Early spellings include Wincelburgh (1189); Wynchburghe (1377); from 'wincel' and 'burh' meaning 'Town in the nook or angle'. It is possible that it was named after the bend in the Niddry Burn that runs through the town. The early settlement was probably near to Niddry Castle.

After the Battle of Bannockburn in 1314, Sir James Douglas followed King Edward II and the remnants of his army to Winchburgh. Both sides rested at Winchburgh before riding on to Dunbar, where King Edward took ship for England.

To bayt thar hors that wer wery,
And Douglas and his cumpany
