Woods has agreed to play in a two-day event organized by Irish racehorse owner J.P. McManus.
The 36-hole pro-am will be held at Adare Manor, which is a former Irish Open venue, on July 5-6, the start of the week before the British Open at St Andrews.
The last J.P. McManus pro-am in 2005 raised 30 million pounds ($36 million) for nominated charities.
In a statement issued by the organizers, Woods said: "Like my own Foundation, I understand the importance and necessity of raising funds to help deserving individuals. This tournament does just that."
The Tiger Woods Foundation provides educational support programs and a learning center for young people.
