The party of the exiled former president Mohamed Nasheed said the unilateral decision to pull out of the 53-member bloc was another example of how Yameen was turning the honeymoon islands into a diplomatic pariah.
"President Yameen has made the Maldives a very isolated place," the Maldivian Democratic Party (MDP) said in a statement.
"This is an absolute despotic move, which says much about the Yameen regime and its political posturing and disregard for international or public opinion."
Nasheed secured political asylum in Britain earlier this year after travelling to London for medical treatment while on prison leave from a controversial 13-year jail sentence.
The country of 340,000 Sunni Muslims is famed for its coral-fringed islands but has been gripped by political unrest since the fall of Nasheed and there are regular anti-government protests.
The Commonwealth had put Male on notice after Nasheed stood down as president in 2012 and said he had been forced out in a coup.
Yameen's government said Thursday that it had been treated "unjustly and unfairly" by the Commonwealth, a voluntary association of more than 50 countries, mostly former territories of the British empire.
"The decision to leave the Commonwealth was difficult, but inevitable," said a statement from the foreign ministry. It also accused the London-based Commonwealth Secretariat of interfering in its affairs.
The Commonwealth's watchdog committee of foreign ministers last month voiced "deep disappointment at the lack of progress" in the Maldives.
