James Warden (1 March 1820 – 24 October 1904) was a Scottish-born Australian politician.
Around 1844 he arrived at Hobart and then went to New South Wales, settling at Ulladulla where he became a ship builder.
In 1855 he turned to farming, purchasing the Boolgata estate in the pioneer settlement of Yatte Yattah (north or present day Milton).
In 1871 he was elected to the New South Wales Legislative Assembly for Shoalhaven, serving until his retirement in 1877.
His nephew, Winter Warden, served in the New South Wales Legislative Council.
