Gladsmuir (Scottish Gaelic: Sliabh a' Chlamhain) is a village and parish in East Lothian, Scotland, situated on the A199 and near Tranent and Prestonpans.

[3] Scottish writer George Godfrey Cunningham (c. 1802–1860) lived at Redcol in Gladsmuir parish.

The interior was destroyed by a fire in 1886 and restored by architect John Farquharson of Haddington with later improvements made in 1929.

[7] Gladsmuir parish was created in 1692 and in its original form it reached the southern shores of the Firth of Forth and extended to an area of 10 square miles.

Distinctively white bricks and roof tiles were produced locally, while the coal mines employed 50 miners, in addition to 30 women and 36 boys in 1836.
