Garleton Castle is a courtyard castle, dating from the sixteenth century, about 1.5 miles (2.4 km) north of Haddington, just north of the Garleton Hills in East Lothian, Scotland.

[1] Garleton Castle once comprised three blocks within a curtain wall,[1] but the main L-plan tower, which had two wings, is mostly demolished.

[3] The remains of the castle are protected as a category B listed building and as a Scheduled Ancient Monument.

[3] It is said the building was haunted by an apparition of a man at one stage, while the sound of heavy footsteps is said to have been heard.

[1] It is possible that Sir David Lyndsay, who wrote Ane Pleasant Satyre of the Thrie Estaitis was born in an earlier building at this site, in 1486.
