James O'Loghlin (politician)

James Vincent O'Loghlin (25 November 1852 – 4 December 1925) was an Australian politician.

O'Loghlin was a member of the South Australian Legislative Council from 1888 to 1902, representing the Northern District, and was Chief Secretary under Charles Kingston from 1896 to 1899. He lost his Legislative Council seat in 1902; though he had been a liberal in state politics, he made unsuccessful campaigns for the Australian Senate as an Australian Labor Party candidate at the 1901 federal election and 1906 federal election. He was briefly appointed as a Labor Senator to a casual vacancy in 1907, but it was invalidated following an electoral dispute. He returned to state politics in 1910–1912, winning the South Australian House of Assembly seat of Flinders for Labor, but losing after one term.

He was elected to the Senate at his third attempt as a Labor candidate at the 1913 federal election, served overseas in World War I while in office, and remained with the Labor Party during the 1916 Labor split. He left office in 1920 after being defeated at the 1919 federal election, but was re-elected at the 1922 election, resuming his seat from 1923 until his death in 1925.
