Sir Patrick Alfred Jennings, KCMG (20 March 1831 – 11 July 1897) was an Irish-Australian politician and Premier of New South Wales.

In 1852 he went to Australia and engaged in gold mining at St Arnaud, Victoria,[2] but soon became a shop keeper, and then moved into quartz-crushing and bought a large pastoral property on the Murrumbidgee River.

[3] Jennings was elected to the assembly again in 1880 as member for the Bogan and from January to July 1883 was Vice-President of the Executive Council in the ministry of Sir Alexander Stuart.

He was nominated to the Legislative Council in 1890, and was one of the New South Wales representatives at the federal convention held at Sydney in 1891, but did not take a prominent part in the proceedings.

He was vice-president of the Agricultural Society of New South Wales from 1876 to 1887 and helped to procure the Moore Park site for the Sydney Royal Easter Show.

Jennings was an amiable, cultivated man much interested in art and music; he contributed £1100 to Sydney University towards the cost of an organ for the great hall.
