Conservative Prime Minister Erna Solberg’s party has ruled the oil-rich country in a coalition government since 2013.
The main opposition Labour party is challenging, but it is likely whichever of the two main groups return the most lawmakers to Norway’s 169-seat parliament, a deal with smaller parties will be necessary to form a government.
A selection of liberals, rural centrists, Greens and socialists are also running.
Among the hopefuls is Espen Barth Eide, the former UN envoy on Cyprus, who is running for the Labour party.
Polls opened at 9 a.m. local time (1100GMT). Around 3.6 million people are eligible to vote.
