Saudi website sabq.org is reporting 20 women have been elected to councils around the country.
The ban on women voting and standing in elections was lifted by the conservative kingdom's late ruler, King Abdullah, in 2011.
It was the first time Saudi Arabian women were allowed to vote and to be candidates in elections.
Saudi women are still forbidden to drive a vehicle and are legally dependent on a male relative to approve almost all their major life decisions.
The preliminary results of Saturday's elections were announced by local districts.
At least four women are confirmed elected to public office in the country's capital, Riyadh.
The Mayor of Riyadh, Ibrahim Al-Sultan, says he's delighted.
"And we are very glad for these results and looking for those winners that will participate in our council and we will see the fruits of their participation."
State media says women have also been elected to councils in the cities of Mecca, Jawf and Tabuk.
In a country where royalty holds extensive executive powers, municipal councils are limited to advising local government and helping oversee budgets.
However female voter Haifa al-Habibi says she is hopeful for a better future.
"I'm really proud that we're forming our future. We're doing history now. And, we're opening the door for much more females to come and participate."
It's the third time in history that the Saudi kingdom has held elections.
There were no elections in the 40 years between 1965 and 2005.
The municipal council is the only government body in which Saudi citizens can elect their representatives.
Nearly 7,000 candidates competed for over 2,100 council seats in local councils, of which over 900 candidates were females.
President of the Municipal Election Committee, Gadiia al-Kahtani, says many female voters took to the polls.
"We've held two municipal elections and this time is the first time that females are allowed to participate. We have accumulated quite a number of voters, with about 600,000 voters this time, and about 130,000 among them are female, taking up about 24 per cent of the overall registered voters."
The move became possible when the late King Abdullah announced in 2011 that women would be able to vote in this election.
Steps were taken to encourage women to have a bigger public role, with policies to increase women's attendance at university and encourage female employment.
Before he died in January, King Abdullah appointed 30 women to the country's top advisory Shura Council.
