Great Britain's Andy Murray during practice at the Aegon Championships at Queen's Club in London June 19, 2017.
The plush tennis courts are situated only a couple of miles from the burnt-out block Grenfell Tower, where at least 79 people are known to have tragically died in last week's fire.
Murray and his managers declined to comment on his decision, saying it was a private matter.
The Scot, playing at the event he's won on five separate occasions as world No. 1 for the first time, was well below par and suffered a shock defeat to the lucky loser.
He has been a generous supporter of charities throughout his career and has helped with a number of charitable causes but has never sought publicity for his personal donations.
Banned materials suspected in London fire
Tailored bereavement support for families of the victims, those missing or people affected by the tragedy will also be provided. Police also identified the first known victim of the fire, 23-year-old Mohammed Al-Habjali, who lived in Grenfell Tower.
This is nothing new for Murray, who donated £73,000 in Queen's winnings in 2013 to the Royal Marsden Centre, where his Davis Cup doubles partner, Ross Hutchins, was treated successfully for Hodgkin's lymphoma.
The two-time Wimbledon champion is now gearing up to defend his title at Queen's Club, with his opening match taking place today against Aljaž Bedene.
In 2009 Murray joined David Beckham in launching an anti-malaria campaign and in 2014 he became a global ambassador for the World Wildlife Fund in support of its fight against the illegal wildlife trade and poaching.
In 2015, Murray also helped raised £83,000 for humanitarian charity Unicef.
