The country's Shiite opposition has called for voters to boycott the election on Saturday.
State media in Bahrain reports that a total of 419 candidates are running for municipal and parliamentary seats. Any candidates that do not secure more than 50 per cent of the vote will head to a runoff a week later.
The elections, however, are unlikely to diffuse tensions between Bahrain's Sunni monarchy and Shiite activists who continue to protest for greater rights and a greater say in government.
The elections are being watched closely by Bahrain's Gulf neighbors and Washington. Bahrain hosts the US Navy's 5th Fleet and is part of the US-led coalition striking the Islamic State group.
