Frederick Alexander Lindemann, 1st Viscount Cherwell, CH, PC, FRS (/ˈtʃɑːrwɛl/ CHAR-wel; 5 April 1886 – 3 July 1957) was a British physicist who was prime scientific adviser to Winston Churchill in World War II.

He was involved in the development of radar and infra-red guidance systems. He was sceptical of the first reports of the enemy's V-weapons programme. He pressed the case for the strategic area bombing of cities.

His abiding influence on Churchill stemmed from close personal friendship, as a member of the latter's country-house set. In Churchill's second government, he was given a seat in the cabinet, and later created Viscount Cherwell of Oxford.
