Martin's Heron is an area of Bracknell (a town in Berkshire, UK, just west of London). The name Martin's Heron is frequently misheard, and its name is a source of much confusion. It has nothing to do with the avian Heron but stems from the old English word for meadow - Hern.

Martins Heron is well known locally as being the site of Harry Potter's house. The recent filmed version of JK Rowling's famous story was filmed partly on location. The external scenes with the actor Daniel Radcliffe playing Harry Potter at his house were shot on location at a house in Picket Post Close, Martin's Heron.

Martin's Heron also boasts a railway station Martin's Heron Station, which serves commuters travelling to London Waterloo and Reading, Berkshire. The train station is very small but is manned during office hours, and is equipped with CCTV. The train station is situated right next to a Tesco supermarket, and indeed was built by the supermarket chain, as a precondition of the supermarket being built.

Martin's Heron Tesco is also used for filming. It is one of the very few Tesco supermarkets in the country that is not open on Sunday, owing to concerns from local residents. It is therefore used as a filming location for all the Tesco television adverts featuring Prunella Scales and Jane Horrocks among others.
