The 2018 New Brunswick general election was held on September 24, 2018,Legislative Assembly Act, Section 2(4). to elect the 49 members of the 59th New Brunswick Legislature, the governing house of the province of New Brunswick, Canada.

Two smaller parties — the People's Alliance and the Greens — made breakthroughs, winning three seats each, and potentially holding the balance of power. The People's Alliance entered the legislature for the first time, while the Greens increased their seat count from one. This marked the first time since the 1991 election that four parties won representation in the legislature. The election was also contested by the provincial New Democrats, newcomers KISS NB, and eight independents.

This is the first election since 1920 that did not return a majority for any party. The Progressive Conservatives won the most seats, with 22, but incumbent Liberal Premier Brian Gallant, whose party secured only 21 seats despite winning the popular vote by six percentage points, indicated that he would seek the confidence of the legislature and attempt to form a minority government.

On September 25, Gallant met with the Lieutenant Governor Jocelyne Roy-Vienneau and received permission to continue in office. On November 2, Gallant's minority government was defeated in a non-confidence vote. On November 9, Progressive Conservative leader Blaine Higgs was sworn in as premier with a minority government.

Aftermath

On election night, Higgs claimed victory, saying his team had received a mandate; however, Gallant did not resign, instead stating his intent to remain in office by securing support on a vote-by-vote basis. The following day, Gallant met with Lieutenant Governor Jocelyne Roy-Vienneau and received permission to continue in office and attempt to seek confidence of the legislature. On September 27, Higgs met with Roy-Vienneau, and was told that if Gallant was unable to secure the confidence of the House, he would be called on to form government; shortly afterwards, Higgs called on Gallant to either resign or immediately recall the legislature.

In the immediate aftermath of the election, both Kris Austin of the People's Alliance and David Coon of the Green Party were noncommittal in their support: Austin pledged to work with any party willing to work with him, but said the party won't sacrifice its "values and ideals" to do so; while Coon said his caucus would take time to figure out how they would align themselves, but would not be able to work with anyone uncommitted to rights for linguistic minorities or combatting climate change. Gallant opted to pursue a partnership with the Green Party, ruling out any arrangement with the PCs or PA because they don't share Liberal "values". Higgs initially ruled out any formal agreements with other parties, but later said that a four-year agreement would be ideal for stability—pointing to the confidence and supply deal that the British Columbia NDP and Greens negotiated following the province's inconclusive 2017 election as an example.

Austin agreed to support to a Progressive Conservative government for 18 months, though no formal agreement was made. Coon said his party would negotiate with both the Liberals and Progressive Conservatives. On October 10, Coon announced that the Green Party would not formally side with either party, and would base their votes on their own "declaration of intent". Accordingly, Coon said that their support for the throne speech depends on its "merits", and that his caucus would be free to vote their own way on the speech.

The results drew notice elsewhere in Canada. Parti Québécois leader Jean-François Lisée described the results as "an advertisement for our proposal for proportional representation." Andrew Weaver, leader of the BC Greens, suggested that Coon should make an agreement with the Progressive Conservatives. The Globe and Mail published an editorial calling for electoral reform, as did National Post columnist Andrew Coyne.

On November 1, Gallant's Liberal minority government was defeated by a non-confidence vote (25–23) by the opposition Progressive Conservatives and People's Alliance. On November 9, Blaine Higgs was sworn in as premier.
