Albert "Jupp" Gardiner (30 July 1867 – 14 August 1952) was an Australian politician who served as a Senator for New South Wales from 1910 to 1926 and again briefly in 1928.

[2][3] His first wife was elected to the New South Wales Labor Party's executive in January 1906 with Kate Dwyer, Harriet Powell, the 1903 parliamentary candidate Selina Siggins, Mary Anne Grant, Edith Bethel and Maggie Hall.

A filibuster in 1918 delivered Federal Parliament's longest speech at 12 hours and 40 minutes (the combined Parnell-Bressington filibuster in the South Australian upper house went for over 13 hours); this forced the introduction of a time limit on future speeches.

In 1926, he lost his Senate seat, but he filled a casual vacancy for five months in 1928, despite expulsion from the Lang-led state branch of the party.

[5] He played rugby union as a forward and represented New South Wales against New Zealand and Queensland in 1897 and against England in 1899.
