Percy Birtchnell (8 April 1910 – 12 March 1986) was a British writer and historian.

He was especially noted for his writing about the history of his home town of Berkhamsted in West Hertfordshire.

His menswear shop later moved west along the High Street to new premises.

Birtchnell's menswear shop continued to trade after his death and closed in 2010.

Following structural damage, the building collapsed unexpectedly in January 2011 and was demolished.
