Ricky Martin is being honoured for his work to encourage equal rights for the gay community.
The 39-year-old Puerto Rican pop singer, who came out last year, will receive the Vito Russo award from the Gay & Lesbian Alliance Against Defamation (GLAAD) at its annual Media Awards in New York next month.
Glee star Kristin Chenoweth is also being honoured by the organisation for her work to promote better understanding.
GLAAD President Jarrett Barrios said: "Ricky coming out was a game changer for many gay and transgender Latino children, who for too long did not have many out gay people to look up to.
"Through his music, videos and interviews, Ricky has sent an important message that our community wants the same things all people do: an equal chance to raise our families and take care of our loved ones."
Kristin, who played boozy April Rhodes in Glee, last year publicly defended gay actors' ability to play straight roles.
She will be presented with the Vanguard Award at an event in Los Angeles on April 10.
"When allies like Kristin take such powerful stands against anti-gay sentiments in the media, it sends an important message of equality," Jarrett added.
"It is a privilege to honour such a talented and conscientious advocate for fairness towards the LGBT community."
