Leading opponents are boycotting the vote, accusing Azerbaijani authorities of persecuting the opposition, muzzling the media and fixing previous polls.
The names of six other candidates will appear alongside Aliyev on the ballot, but all are loyal to the authorities and some have not even bothered to campaign.
The government has said Aliyev’s popularity is unassailable, in part thanks to an oil boom driving one of the fastest-growing economies in the world, despite the global financial crisis.
Analysts say the only question is by how wide a margin the 46-year-old president, son of Heydar Aliyev, the Caspian state’s previous president, will surpass the other contenders.
Heydar Aliyev dominated political life in the country for more than 30 years.
Fuelled by energy exports, Azerbaijan’s economy grew by 26 per cent last year, among the highest growth rates in the world, despite widespread corruption.
Since coming to power in 2003 after his father’s death, Aliyev has walked a tightrope between Moscow and Washington as the two vied for access to the vast energy resources of the Caspian Sea.
Despite criticism of his democratic record, Washington considers Aliyev as a key energy partner.
Azerbaijan is the starting point for a strategic corridor of pipelines delivering oil and gas from the Caspian Sea to Turkey, and on to Western markets.
But analysts say Aliyev will remain wary of angering Moscow, especially after the Georgia-Russia war in August showed how far the Kremlin was willing to go to protect its interests in the region.
