The BT Tower is a communications tower in Fitzrovia, London, England, constructed in 1964. At the time of its completion it was known as the Museum Radio Tower, referring to its use by the neighbouring Museum Telephone Exchange. Subsequent changes in ownership caused it to become the Post Office Tower and Telecom Tower before it gained its current name in 1991. Since 2024 it has been owned by MCR Hotels. In 2003 Historic England designated it as a Grade II listed building.
