The Tolbooth in Aberdeen, Scotland is a 17th-century former jail which is now operated as a museum. It was built between 1616 and 1629 and is attached to Aberdeen Sheriff Court on the city centre's Union Street.
The museum contains exhibits of prison cells and various police and law and order related items.
The building is claimed to be one of the most haunted buildings in Aberdeen and has been subject to many investigations by paranormal investigation teams East Scotland Paranormal and James Warrender's: The Ghost Network. The most notable investigation was in April 2009 when the Livingtv series Most Haunted visited the building. The episode aired in December 2009.
