Kennedia retrorsa is a species of flowering plant in the family Fabaceae and is endemic to New South Wales.

Kennedia retrorsa is a vigorous climbing herb covered with rust-coloured or white hairs.

Flowering mainly occurs from September to December and the fruit is a densely hairy, flattened pod about 60 mm (2.4 in) long.

[7] This kennedia is only known from the Goulburn River National Park where it grows in cool, damp and rocky places in a range of habitats, usually in sandy soil.

[4][5] Kennedia retrorsa is listed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and the New South Wales Government Biodiversity Conservation Act 2016.
