Chris Froome will face potential Tour de France rivals Alberto Contador, Nairo Quintana and Vincenzo Nibali at Tirreno-Adriatico later this month.
The quartet have all been listed as taking part in the seven-day Italian stage race, which runs from March 11-17, by organisers RCS Sport.
It will be the first time the dominant four Grand Tour winners have all raced in the same WorldTour event, RCS Sport said.
The race starts with a team time trial, includes one summit finish and ends with a 10km individual time trial.
Contador (Tinkoff-Saxo) is the defending champion of the "Race of the Two Seas" and has won all three Grand Tours, as has Nibali, who won Tirreno-Adriatico in 2012 and 2013.
Froome, the 2013 Tour de France winner, will lead a Team Sky squad that is also slated to include Elia Viviani.
The Italian will contest the sprints against Mark Cavendish (Etixx - Quick-Step) and Marcel Kittel (Giant-Alpecin), who has taken the Briton's mantle as the world's top sprinter in recent seasons.
