Sir Norbert Michael Keenan QC (30 January 1864 – 24 April 1954) was an Australian lawyer and politician who was a member of the Legislative Assembly of Western Australia from 1905 to 1911 and again from 1930 to 1950.

[3] Keenan emigrated to Western Australia in April 1895, and settled in Kalgoorlie, where he represented the interests of British investors on the Eastern Goldfields.

[7] At the 1904 state election, Keenan unsuccessfully contested the seat of Kalgoorlie as an independent, losing to the sitting Labor member, William Dartnell Johnson.

While in office, he chaired a Legislative Assembly select committee into Western Australia's electoral system, which recommended that the state adopt preferential voting and make various other changes.

[4] After a gap of over 18 years, Keenan re-entered parliament at the 1930 state election, winning the newly created seat of Nedlands for the Nationalist Party.

[8] Just eleven days after being elected, he was included in the new ministry formed by Sir James Mitchell, taking the positions of Chief Secretary and Minister for Education.

[3] While in charge of the Education Department, Keenan made the unpopular decision to close Claremont Teachers College indefinitely, to save money during the Great Depression.

Keenan polled only 23.3 percent of the first-preference vote, which was not enough to make the final two-candidate-preferred count, and the eventual victor was David Grayden, a 25-year-old leader of the party's youth wing.
