Underwood will start singing "Waiting All Day for Sunday Night" Sept. 8.
The opening theme will continue each week kicking off "Sunday Night Football" every Sunday night throughout the NFL season on NBC.
"I am thrilled to be a part of NBC's 'Sunday Night Football' and am so honored they asked me," Underwood said in a statement Tuesday. "I have always loved football season, and it is so exciting to now become part of it every Sunday night."
"Carrie Underwood was our first and only choice to perform the 'Sunday Night Football' opening," said "SNF" producer Fred Gaudelli. "She's one of America's most popular entertainers and the perfect fit for our show."
P!nk and Faith Hill previously performed the "SNF" theme.
