Mayne died, tired and embittered, at his home in Chester Square on Boxing Day 1868.
 Although he had made mistakes, he had achieved astonishing things.
 The original force of less than 1,000 men had grown during his commissionership to nearly 8,000.
 The area it policed had increased to ten times its original area, and the idea had spread to every county and town in the country.
Mayne was buried in Kensal Green Cemetery, London.
He was survived by his widow, Georgina Marianne Catherine, eldest daughter of Thomas Carvick of Wyke Manor, Yorkshire, whom he had married in 1831, and children including his son, Rear-Admiral Richard Mayne of the Royal Navy.

In the television film The Suspicions of Mr Whicher (2011) and its 2013 sequel he was played by Tim Pigott-Smith.
