Sir Walter Dwyer (27 August 1875 – 22 March 1950) was an Australian lawyer, politician, and judge.

He was a member of the Legislative Assembly of Western Australia from 1911 to 1914, and later serving as the presiding judge on the State Court of Arbitration from 1926 to 1945.

[2] After leaving parliament, Dwyer developed a reputation as one of Perth's best labour lawyers.

He was also a prominent Irish nationalist, and in 1919 was arrested and fined for leading a prohibited Saint Patrick's Day march.

[5] He served in the position until 1945, and developed a reputation for fairness and impartiality, with a later source describing Western Australia's lack of industrial conflict as "largely due to the confidence in the court that he had created".
