German Chancellor Angela Merkel will likely serve another term.
The Social Democratic Party is predicted to come in second, and the far-right Alternative for Germany party, or AfD, in third.
The AfD's projected success in this election would make it first far-right party to have members reach Germany's Parliament since the National Socialist German Workers' Party, also known as the Nazi Party, fell at the end of World War II.
This is also the first national vote since Germany, under Merkel's leadership, opened the country's doors to almost 900,000 migrants and refugees.
The upcoming term would be a busy one for Merkel. Germany will play a major role in facilitating the U.K.'s exit from the European Union.
The chancellor will also be tasked with combating terrorism, climate change and an increasingly threatening North Korea.
