The Katharine Burr Blodgett Medal and Prize is a gold medal awarded annually by the Institute of Physics to "recognise contributions to the organisation or application of physics in an industrial or commercial context."

The medal is accompanied by a prize of £1000.

[1] At its inception in 2008, the award was named the "Business and Innovation Medal".

In 2012, it was renamed the "Swan Medal and Prize" in memory of Sir Joseph Swan, a chemist, physicist, and early developer of the incandescent light bulb.

Since 2016, the award was renamed again to commemorate Katharine Burr Blodgett, inventor of low-reflectance "invisible" glass (Langmuir–Blodgett film), and the first woman to receive a degree in physics from Cambridge University.
