Outgoing president: Susilo Bambang Yudhoyono
Former army general Susilo Bambang Yudhoyono won Indonesia's first-ever direct presidential elections in September 2004, in what was hailed as the first peaceful transition of power in Indonesia's history.
He was re-elected in July 2009 in a landslide victory on the back of improved security and strong growth in Southeast Asia's biggest economy.
Mr Yudhoyono is credited with having ushered in an era of financial stability. He also cultivated an image as a tough corruption fighter with high moral integrity, but the sentencing in 2012 of a former official of the president's party caused embarrassment.
The first year of Mr Yudhoyono's first term brought perhaps his biggest challenge, the 2004 Asian tsunami disaster. His administration also won international plaudits for signing a peace deal in 2005 with separatist rebels in Aceh province.
Barred from standing for a third term, Mr Yudhoyono was set to be replaced in October 2014 by Jakarta governor Joko Widodo.
President-elect: Joko Widodo
Joko Widodo won a closely fought presidential election in July 2014 on promises to break with the authoritarian past, improve welfare for the poor and take on corruption.
The election commission declared the Jakarta governor the winner with 53% of the vote. He is set to be inaugurated in October.
His rival, former army general Prabowo Subianto, who won 47%, alleged widespread fraud and said he would challenge the result in court.
Mr Widodo is seen by many as relatively untainted by the county's endemic corruption and in touch with ordinary Indonesians as a result of his humble background.
Known as "Jokowi", the former furniture maker is especially popular with the urban and rural young.
His campaign platform called for "mind-set revolution" to end the corruption, nepotism and intolerance Mr Widodo believes flourished during the 31-year-long dictatorship of former President Suharto.
He also promised a strong focus on education and modern technology, including e-governance.
Critics say he lacks political experience and will struggle to push through his agenda, as his Indonesian Democratic Party-Struggle (PDI-P), has only 37% of seats in parliament.
Opponents claimed he would be the puppet of the PDI-P's veteran leader, Megawati Sukarnoputri, a former president and daughter of Indonesia's independence leader, Sukarno. Mr Widodo's allies insist he will be his own man.
Born in 1961 in Solo as the son of a wood-seller, Mr Widodo was elected mayor of Solo - a city in the centre of Java - in 2005 and gained popularity with policies aimed at boosting small and local businesses.
Mr Widodo then went on to run for the position of governor of Jakarta, winning an emphatic victory in 2012.
