Tonight's national anthem performer depends on the event in question:

• At the 2025 Super Bowl LIX on February 9, 2025, the national anthem was sung by Jon Batiste, a seven-time Grammy-winning artist from New Orleans. He delivered a lively rendition before the Kansas City Chiefs and Philadelphia Eagles game

• For the 2025 Indy 500, the national anthem was sung by Natalie Grant, a Grammy-nominated Christian and gospel vocalist

• At an NFL Draft event in Green Bay on April 24, 2025, Stephen Wilson Jr. performed the national anthem

• On May 21, 2025, Nikki Hayes sang the national anthem for the Phoenix Mercury basketball team

• For the WWE Royal Rumble event, Lanie Gardner performed the national anthem, as indicated on TikTok

If you specify the event or location for "tonight," I can provide the exact singer.
