Roza Otunbaeva's appeal came to the Supreme Court after an earlier rejection by a Bishkek district court.
Otunbaeva leads the opposition Ata-Jurt movement. Her application to participate in the polls was originally accepted, but later retracted for unclear reasons.
Ata-Jurt officials say the retraction was politically motivated. Party officials say they are planning a rally in Bishkek tomorrow to protest today's Supreme Court ruling.
Otunbaeva now plans to take her appeal to the Constitutional Court.
