The opposition, which held a peaceful rally in the capital last Wednesday, says the 6 November vote was fraudulent and wants new elections to be held.
International organizations have also criticized the polls, saying they failed to meet international election standards.
Authorities have warned that the protest will be forcefully dispersed if the rally overstays its legal permit.
According to official results, the ruling Yeni Azerbaijan party of President Ilham Aliyev won the elections, taking about half the seats in the 125-member national assembly.
In comments carried on 12 November by state-run media, Aliyev ruled out any popular revolution in Azerbaijan.
