Kirby Muxloe Castle, known also as Kirby Castle is an unfinished 15th century fortified manor house in Kirby Muxloe, Leicestershire, England.
It was begun in 1480 by William Hastings, 1st Baron Hastings, during the period of the Wars of the Roses. However work stopped at the castle when he was executed in 1483 for treason by Richard III and it was never completed. It is now an English Heritage property.
The castle has recently undergone extensive restoration work.
It is open to visitors on Saturdays, Sundays and Bank Holidays from 1st May until 31st August.
