Andreja Koblar (née Grašič, born 2 September 1971, in Kranj, SFR Yugoslavia) is a former Slovenian biathlete.
She made her debut in the Biathlon World Cup in the season opener in Bad Gastein, where she finished 24th at the 20 km individual.
She was most notably consistent in the individual event ever since where she claimed three World Cup victories (1995-96 in Osrblie, 1996/97 in Nozawa Onsen and 1997/98 in Östersund).
Since the 35-year-old failed to impress the coaches at the national competition to qualify for the 2006-07 World Cup season, she decided to retire from the sport.
[1] On 17 January 2007, at the World Cup in Slovenia she was allowed to start in her farewell race and her fans cheered and welcomed her at the finish line to honor all the great service she had done for her country.
