Lewis Windermere Nott (12 February 1886 – 27 October 1951) was an Australian politician, medical practitioner and hospital superintendent.

He then studied assaying at the School of Mines and Industries, Ballarat, Victoria before undertaking a medical degree at the University of Sydney.

At the outbreak of World War One he enlisted in the Royal Scots and rose captain and made adjutant.

On graduation in 1918 he joined the Royal Army Medical Corps and in 1919 worked at the Pilkington Special (Orthopaedic) Hospital, St Helens, Lancashire.

[2] Nott returned to Australia and took part in the campaign against hookworm and then was appointed medical superintendent of Mackay District Hospital.

In this contest he unexpectedly defeated the Australian Labor Party candidate Ted Theodore, who had resigned as Premier of Queensland to enter federal politics (he had to wait for a by-election in 1927 in a Sydney seat before he was successful).

In 1949, he was elected as an independent as the first representative of the Division of Australian Capital Territory in the Federal Parliament, where he had unlimited speaking rights but could only vote on matters affecting the ACT.
