The Saskatchewan Party (SP or Sask Party) is a conservative political party in the Canadian province of Saskatchewan. The party was founded in 1997 by a coalition of former provincial Progressive Conservative and Liberal Party members who sought to unite opposition to the governing New Democratic Party. Since 2007, the Saskatchewan Party has been the province's governing party, and both the party and the province are currently led by Premier Scott Moe.

Since first being elected to a majority government in 2007, the Saskatchewan Party has enjoyed a run of electoral success not seen in the province since the days of Tommy Douglas's Co-operative Commonwealth Federation. In 2024, the SP was elected to its fifth consecutive majority government, a feat not achieved since the CCF led five majority governments between 1944 and 1964. This success has led observers to declare the SP the province's new natural governing party.

Brad Wall was the first SP leader to become Premier in 2007. The party took power at a time of soaring natural resource prices, which helped to spur economic and population growth. A downturn in resource prices beginning in 2014 created challenges for the province's economy, and in the years since the provincial debt has reached historic levels. Wall announced his retirement in 2017 and he was succeeded by Moe in 2018. Under Wall's early leadership, the SP was considered to be a centre-right party, albeit one with a neoliberal and Christian conservative basis. In later years (and particularly under Moe's leadership), the party is considered to have taken a turn further to the right. Under both premiers, and especially since the election of a Liberal federal government in 2015, the party has increasingly focused its attention on the federal government and espoused sentiments of western alienation within the Canadian federation.

The Saskatchewan Party arose from a distinct political climate in the 1990s. The Progressive Conservatives led two consecutive majority governments from 1982 to 1991 under the leadership of Grant Devine. However, economic challenges, the party's profligate spending (which left the province on the brink of bankruptcy), a close association with Brian Mulroney's unpopular federal PCs, and a major expense fraud scandal that resulted in prison time for several members of the party all severely damaged the PCs. Under the leadership of Bill Boyd, the PCs lost nearly half of their vote share in 1995 compared to 1991, and the party was reduced to five MLAs. The Liberal Party, meanwhile, despite returning to Official Opposition status in 1995 for the first time since 1975, was being weakened by internal disputes. The New Democratic Party (NDP) under Roy Romanow took power in 1991, and rapidly addressed the fiscal crisis, balancing the province's finances by 1995. However, this process involved numerous cuts to services that were seen as disproportionately affecting rural residents, deepening an urban-rural divide in the province that had already been widened by the PC emphasis on rural issues throughout the 1980s.

With neither the PCs nor the Liberals seeing a clear path to defeating the NDP, discussions about a merger began within the caucuses in July 1997. Although unsuccessful at first, four MLAs from each party, all representing rural districts, agreed to walk away from their parties and form a new one. In August 1997, PC MLAs Boyd, Dan D'Autremont, Ben Heppner, and Don Toth joined former Liberal MLAs Bob Bjornerud, June Draude, Rod Gatefoer, and Ken Krawetz in announcing the founding of the Saskatchewan Party. The new party was officially registered on September 17, and with eight sitting MLAs, took over the status of Official Opposition. Krawetz, who had been serving as the leader of the Opposition with the Liberals, maintained that role when he became the interim leader of the new party. Its formation was challenged by Reform Party members who planned to establish a provincial affiliate, accusing the new party of performative populism. Concerned about possible right-wing competition, the November founding convention adopted grassroots provisions on voter recall, fixed election dates, free votes for party MLAs and referendums on abortion and VLT. While the SP embraced some Reform Party policies and thereby won the favour of their political operatives, its formulation has been described as a movement by political elites.

Neither the PCs nor the Liberals disbanded after this merger of former party MLAs. However, while the Liberals ran a full slate of candidates in the 1999 election, with four being elected, the Progressive Conservatives effectively went dormant, running only paper candidates to keep the party registered over the next election cycles. This, along with the broad migration of PC members and staff to the new party, led to accusations by the NDP and the Liberal Party that the new party was merely a rebranding of the scandal-plagued PCs. Romanow often referred to the new party as the "Saskatories".

In April 1998, former Member of Parliament and Reform Party house leader Elwin Hermanson was elected the party's first leader. Hermanson defeated former Liberal MLA Gantefoer and political newcomer Yogi Huyghebaert for the position. Since Hermanson did not have a seat in the legislature, Krawetz remained as interim house Opposition leader. The new leader stated that while people "know I have the best interests of the agriculture industry and rural Saskatchewan at heart because that's where I still live", the new party was "not anti-urban." Hermanson declined to run in a 1998 Saskatoon by-election, instead waiting for the next general election to run for a seat. Under Hermanson, the party put forward an ambitious fiscal conservative platform, calling for major corporate and income tax cuts. These policies were joined by a number of controversial and social conservative policies, from a commitment to consider privatizing crown corporations to work-for-welfare policies and an end to public affirmative action. Limited attention was paid to federal-provincial relations, while proposing to Romanow and Melenchuck to act as a "united front" to exert pressure on agricultural issues.

Hermanson led the fledgling party into its first election in 1999 on this platform. The party had a strong showing, narrowly edging out the NDP in the popular vote and sweeping rural districts across the province, demonstrating the growing cleavage between urban and rural areas; the party won only a single urban seat. Overall, the SP won 25 seats and reduced the NDP—which won 29—to a minority government.
