Rower Katherine Grainger, swimmer Michael Jamieson and Jade Jones, who won Team GB's first tae kwon do Olympic gold, are lending their support to the campaign to bring the event to Scotland.
Glasgow was short-listed last month as one of three candidates to stage the 2018 Games, going up against Buenos Aires in Argentina and Medellin in Colombia. The final decision will be announced in July.
Grainger, who last summer added gold to her three previous Olympic silver medals, said: "Glasgow has an outstanding track record of hosting major sporting events. Over the years the city has shown it has what it takes to put on a show, and this is exactly what it aims to do in 2018.
"Glasgow 2018 will inspire young people to be champions in their lives. We want to reach out to young people across the world and make 2018 a year to remember for young people."
Olympic silver medallist Jamieson, a former pupil at Glasgow School of Sport at Bellahouston Academy, said: "Having grown up in Glasgow, I am passionate about this bid and the commitment in Glasgow to developing sport at all levels."
The first summer Youth Olympics was held in Singapore in 2010 and the event will be held in Nanjing, China next year.
Jones, who won gold at the 2010 event, said: "I know that Glasgow will be the beginning of a great Olympic career for so many young athletes."
The event sees athletes aged between 15 and 18 compete in all 28 Olympic sports over 12 days.
