The prizes for the year's best on Broadway are to be given out June 8 at Radio City Music Hall.
Jackman previously served as host from 2003-05 and earned an Emmy Award for his 2004 duties at the 58th annual ceremony.
"We are thrilled to have Hugh Jackman return to host the Tony Awards," Jack Sussman, executive vice president of specials, music and live events for CBS Entertainment, said in a statement. "Hugh is the ultimate performer -- actor, singer and dancer -- he does it all, second to none. He is a consummate entertainer and the one you want out there hosting your live television event."
"We are excited that Hugh will be joining us, once again, at Radio City Music Hall to host the 68th annual Tony Awards," Charlotte St. Martin, executive director of The Broadway League, and Heather Hitchens, executive director of the American Theatre Wing, said in a joint statement. "Hugh is an extraordinary talent and loyal supporter of the Broadway community -- whether he is on-stage or in the audience -- and we are honored to have him back as host."
