The National Coalition Party, two other parties, and Finland's far-right Finns Party have agreed to form a coalition government.
The Party, which finished second in the election held in April, had pushed for significant immigration reductions during negotiations.
The other two parties in power will be the Christian Democrats and the Swedish People's Party, both of which speak to minorities.
Former Prime Minister Sanna Marin and her center-left party are no longer in power under the new coalition.
With 48 seats won, the National Coalition Party won the election. With 46 seats, the Finns Party came in second, and Ms. Marin's Social Democratic Party came in third with 43 seats.
Finland frequently sees large alliances between parties with opposing ideologies, so the National Coalition Party could have attempted to form a government with the Social Democratic party.
They disagreed on the economy, and the right-wing party wanted to drastically cut government spending, so it was decided to support these right-wing organizations.
108 of the 200 seats in parliament will belong to the new administration.
Petteri Orpo, the leader of the National Coalition Party, said in a press conference with the three other party leaders in Helsinki, "I am proud of the good programme and the result of the negotiations.
We have had disagreements in the past, and I'm sure they will continue, but what binds us together is our desire to restore order to Finland, Mr. Orpo continued.
The parties' negotiations proved challenging and dragged on for the past 11 weeks, during which Ms. Marin continued to serve as caretaker prime minister.
Conflicts between the Finns Party and the Swedish People's Party were brought on by differences on topics like immigration and the environment.
The Finns Party wants Finland to leave the EU and to put off achieving its 2035 carbon neutrality goal.
Prior to the Finns Party splitting into its two factions, the moderates and the hardliners, it was in coalition with the National Coalition Party. The only group still in power in parliament is the hardliners.
Riikka Purra, the leader of the Finns Party, said, "I would like to thank my colleagues with whom we have been able to reach an agreement.
To get Finland's economy back on track, according to the incoming center-right prime minister, Mr. Orpo.
There is still no date set for the next vote in parliament to confirm Mr. Orpo as prime minister.
