They will also vote for a president, governor and MCA.
After months of vigorous campaigns, the Star looks at the hot MP races to watch in the Tuesday election.
In the 2017 polls, ODM leader Raila Odinga garnered 828,826 votes against President Uhuru Kenyatta's 791,291.
In the constituencies, Uhuru's Jubilee party won nine seats against Raila's seven that went to the ODM fold. Kalonzo Musyoka's Wiper party won one seat in the city.
Uhuru is not running in this election and some dynamics have changed.
The governor’s race, which has attracted nine candidates, has been narrowed down to a two-horse race between UDA's Johnson Sakaja and Polycarp Igathe of Jubilee.
The contest for parliamentary seats has been narrowed down to a battle between Azimio la Umoja One Kenya coalition led by Raila and the Kenya Kwanza led by Deputy President William Ruto.
ODM's Edwin Sifuna will be the Azimio coalition's candidate for the Senate seat while Woman Representative Esther Passaris will be defending her seat on the ODM ticket.
UDA is fronting former Starehe lawmaker Margaret Wanjiru for Senate while Nominated Senator Millicent Omanga will run for Woman Rep.
Some of the hotly contested National Assembly seats include Embakasi West which has 141,878 registered voters.
