Burma's election commission has given the opposition leader permission to participate in April elections, which are seen as a key test of democracy.
The elections are seen as a key test of the long-repressed country's commitment to democratic reforms.
Aung San Suu Kyi previously announced her intention to run in the April elections but was waiting for official approval from the commission, which said it had to scrutinise her eligibility.
The commission said on Monday it had no objection to Suu Kyi's bid and officially accepted her candidacy.
After nearly half a century of military rule, a nominally civilian government took office last March.
The April polls are being held to fill 48 seats.
