Wet Leg's headline set will be punctuated by fireworks from Edinburgh Castle at midnight, marking the start of 2026.
Comedian Susie McCabe will host the event and lead the countdown.
Organisers say the event will "promises to be a night of incredible celebration and music".
The Concert in the Gardens is part of a four-day celebration kicking off on 29 December with a torchlight procession.
A "Night Afore Concert" on 30 December will feature performances from ceilidh bands Peat and Diesel and RuMac.
Revellers will hope the headliner's name is not a bad omen for the event that had to be cancelled last year due to "extreme weather".
Councillor Margaret Graham, culture and communities convener of Edinburgh City Council, said: "Our Hogmanay celebration is not just an Edinburgh tradition, we're known worldwide as the place to be to bring in the bells.
"I'm delighted that this year's Concert in the Gardens will have a strong Scottish supporting line-up. As the home of Hogmanay it promises to be the ultimate party to welcome 2026."
Tickets for Edinburgh's Hogmanay will go on pre-sale on Monday, with a general sale on Tuesday.
