The Scotch Piper Inn, Lydiate, Merseyside, England is the oldest pub of the historic county of Lancashire. The building dates from 1320 and is a Grade II* listed building. It was originally known as "The Royal Oak", and sections of the trunk of the oak tree around which it was built are visible from the tap room. The building retains a thatched roof.
It is located on the A5147, 10 miles (16 km) from Liverpool and 10 miles (16 km) from Southport. It stands close to the site of Lydiate Hall and next to the remains of St Catherine's Chapel.
There is also a well known bike meet every Wednesday, with bikers from up to 20 km away visiting.
Tony Blair once visited the Scotch Piper, in 1999 during his first term as Prime Minister.
In March 2014 it was announced that the current landlord would be vacating the Scotch Piper at the end of the month. This ended a period stretching back since 1961 in which the pub has been run by the same family. A new landlord was to move in immediately at the beginning of April. There was a further change of licensee in November 2016.
The Admiral Taverns pub suffered severe fire damage to its thatched roof on Tuesday 6th December 2016. Fortunately the main structure of the roof and fabric of the building were saved and the pub currently remains closed for repairs.
