William "Bill" Slater (c. 20 May 1890 – 19 June 1960) was an Australian lawyer, politician and diplomat.
Slater is believed to have been born around 20 May 1890 to parents of Irish background in Wangaratta, Victoria. After his father left his family when he was four years old, he and his two siblings were brought up by his mother in Prahran. After briefly attending Armadale State School, Slater left school early to sell newspapers. Being caught and fined for nude swimming in the Yarra River led him to decide to better himself. Using a free library and with support from the Try Boys' Society he was able to educate himself to the point he was able to be employed as an office boy.
As a socialist, Slater refused to enlist with the Australian Imperial Force (AIF) at the beginning of World War I. However, spurred on by the aftermath of the Gallipoli campaign, he decided to enlist with the AIF. His first attempt to enlist was unsuccessful as he was deemed unsuitable for service due to varicose veins. After an operation to fix the ailment he enlisted in December 1915 with the 10th Field Ambulance.
Slater left Melbourne with his unit in June 1916, arriving in Plymouth, England in August of the same year. In November he was disciplined for poor conduct. In July 1917 he was wounded in action, sustaining a gunshot wound to the leg.
While recovering in an English hospital he agreed to stand for election to the Victorian Legislative Assembly. In November 1917 he was elected to the seat of Dundas. The Argus newspaper later reported that fellow patients at the hospital mistook his appointment as a Member of Parliament as being a promotion to the Military Police.
He left for Australia in early 1918. Returning to Australia he was arrested by military police in Fremantle for speaking in defence of John Curtin, then the editor of a trade union newspaper. He was discharged from active service due to a recurrence of his varicose veins. 
On his return to Victoria he was engaged by Maurice Blackburn as an articled clerk. When he was admitted as a barrister and solicitor in 1922 he became a partner in Blackburn's practice which was renamed Blackburn and Slater.
He was Attorney-General and Solicitor General on 5 occasions. In July 1924 he was appointed Attorney-General and Solicitor General in the Prendergast government which only lasted five months. He was given the same cabinet posts under the premierships of Edmond Hogan in 1927–1928 and 1929–1932.
At the 1932 state election, Slater was defeated in Dundas by United Australia Party candidate Athol Cooper. However the closeness of the result prompted a recount, and on 6 September 1932, the Committee of Elections and Qualifications presented its report on the recount to the parliament, which unseated Cooper and declared Slater duly elected.
In 1942 he was appointed by Prime Minister John Curtin as minister to the Soviet Union, the first Australian diplomatic representative to the country. En route to his new appointment he visited the United States, eventually arriving in the Soviet Union in late 1942. He took residence in Kuybyshev in January 1943. After falling ill in April 1943 he returned to Australia in June. Although the official reason given for his early return was illness, speculation in the Australian press centred on a disillusionment with the Soviet version of Socialism.
Under John Cain he was Attorney-General and Solicitor-General between 1945 and 1947 when he lost his seat. In 1949 he returned to Parliament in the Victorian Legislative Council seat of Doutta Galla. He once again served as Attorney-General and Solicitor-General between 1952 and 1955.
