Hugh Percy Murray-Aynsley (8 October 1828 – 22 February 1917) was a 19th-century Member of Parliament in Canterbury, New Zealand.

[4] In 1862, Murray-Aynsley purchased Riverlaw, a rural property at the bottom of Rapaki Track adjacent to the Ōpāwaho / Heathcote River originally owned by Alexander Lean.

He sold Riverlaw in 1905 to George John Smith, who further enlarged the house including the addition of a third storey.

[12] He was a member of the Canterbury Executive Council from 22 July 1862 to 13 November 1863 under Robert Wilkin, and for a few days until his resignation under Thomas Cass.

[13][14] He was Deputy Superintendent from 31 May 1869 to August 1872 and stood in for William Rolleston in 1869 who was in Wellington attending Parliament.

[22][23] The next section of road upstream from here was renamed to Riverlaw Terrace in the following year some months after Murray-Aynsley's death.
