Baron Hylton is a title that has been created twice, once in the Peerage of England and once in the Peerage of the United Kingdom. The first creation came in the Peerage of England 1295 when Robert Hylton was summoned to the Model Parliament as Lord Hylton by writ. His son, Alexander, was called to Parliament in 1332 and 1335, but no further summons were sent for his descendants. Therefore, the title has only been held de jure after the death of the second baron. Indeed, the last baron was Member of Parliament for Carlisle after "inheriting" the title, due to this anomaly. Despite this, the creation is deemed to have fallen into abeyance on the death of the eighteenth baron without male heirs in 1746.

Ammerdown House in Kilmersdon, Somerset, England, was built in 1788. It has been designated as Grade I listed building.
