Any Murray will donate £50 for every ace he scores between now and the end of the year to Unicef's refugee relief efforts.
The Scottish tennis star said he was compelled to help after watching images on the news of children and their families forced to flee conflict.
Murray's sponsors Standard Life, the men's professional tour ATP and British governing body Lawn Tennis Association all said they would match Andy's donations pound for pound, meaning every ace hit will raise £200 for Unicef's work with refugees.
Fans can also contribute to the campaign through a JustGiving campaign.
Having seen the images broadcast on the news in recent weeks I felt I had to do something to help the millions of children and their families who have been forced to flee their homes and had their lives turned upside down.
I’ll get that little bit more satisfaction from each ace I hit knowing that it will be helping Unicef keep children safe. I'm also asking my fans across the world to join with me to and support Unicef’s vital work. Together we can help make a safer world for every child.
So far this season the world No3 has scored 461 aces - the 13th highest on the ATP Tour - meaning he would have personally generated £20,800 and £92,200 as a total with his backers.
