Woods is currently recovering after knee surgery
Tiger Woods will speak at President-elect Barack Obama's inauguration event in Washington DC on Sunday.
"We Are One: The Obama Inaugural Celebration at the Lincoln Memorial" is the first of several events in the run-up to the ceremony on Tuesday.
Woods became the first African-American to win a major at the 1997 US Masters.
The 33-year-old clinched his 14th major victory at the US Open in June but has been not played since after undergoing reconstructive knee surgery.
"I am honoured that I was invited to this historic event and look forward to participating in Sunday's festivities," said Woods, the world number one.
Woods is among several celebrities who will take part in Sunday's event at the Lincoln Memorial, where civil rights leader Martin Luther King Jr delivered his famous "I Have a Dream" speech in 1963.
Others include Hollywood actors Denzel Washington, Jamie Foxx and Queen Latifah and musicians Beyonce, Bono, Bruce Springsteen, Sheryl Crow, James Taylor and Stevie Wonder.
