Remai Modern is a public art museum in Saskatoon, Saskatchewan, Canada. The art museum is situated along the west bank of the South Saskatchewan River, at the River Landing development in Saskatoon's Central Business District. The museum's 11,582 square metres (124,670 sq ft) building was designed by Bruce Kuwabara of KPMB Architects in association with Architecture49.

Plans to create a new art museum in Saskatoon emerged after plans to renovate the Mendel Art Gallery were abandoned in 2009. The new art museum was formally incorporated on 9 July 2009 as the Art Gallery of Saskatchewan. In 2016, the institution was rebranded as Remai Modern by the Saskatoon City Council; after Saskatoon-based entrepreneur and philanthropist Ellen Remai announced a donation of CA$30 million on behalf of the Frank and Ellen Remai Foundation to fund the construction and programming for the museum. Construction for the art museum took place from June 2013 to 2017, and was opened to the public in October 2017.

The museum's permanent collection features over 8,000 works from Canadian and international artists. Its collection includes the collection of the former Mendel Art Gallery; and a collection of more than 400 linocuts and ceramics by Pablo Picasso. In addition to exhibiting works from its collection, the museum organizes exhibitions and hosts a number of travelling exhibitions.

Plans to develop a modern and contemporary art museum began in the late 2000s and early 2010s. These plans originated from expansion and moving plans of the former Mendel Art Gallery, which announced its intention to move to the River Landing development in April 2009. However, in November 2009, the city council of Saskatoon voted to establish a new art museum at the River Landing location. The art museum was formally incorporated on 9 July 2009 as the Art Gallery of Saskatchewan Inc. The new art museum is not considered a direct continuation of the Mendel Art Gallery, although it did inherit its permanent collection after its closure in June 2015. The assets of the Mendel Art Gallery were split between the City of Saskatoon government and the Art Gallery of Saskatchewan following the Mendel's closure.

In 2011, lead patron Ellen Remai donated $15 million toward construction costs of a new art museum, $15 million to support international exhibition programs, and also donated the most comprehensive collection of Picasso linocuts to the future art museum's permanent collection. As a result of the donation, the museum announced it was rebranding as the Remai Art Gallery of Saskatchewan.

The inaugural director and CEO of the museum, Gregory Burke, was appointed in May 2013. Construction for the museum building began on 7 June 2013. Funding to build the museum building came from the federal, provincial, and municipal governments, as well as private donors. The federal government contributed $13,020,000; the provincial government contributed $16,744,000, and the municipal government contributed $30,287,000. The final budget approved to build the museum was $84,634,160, with the remaining $24,095,160 collected through fundraisers and private donors. The museum was later rebranded as Remai Modern Art Gallery of Saskatchewan in April 2014. In doing so, it became the first art museum in Canada to brand themselves specifically for modern art.

During construction for the museum building, the museum's Board of Directors became the subject of controversy. In December 2015, local artists submitted a letter to the Remai Modern's board requesting the removal of board member, John Gormley. In the letter, the artists referred to a Twitter post made by Gormley suggesting violence against Muslims in the wake of the November 2015 Paris attacks. Gormley remained on the board while an independent third-party review was performed. In January 2016, the third-party review found Gormley was not in breach of the Remai Modern's code of conduct. On April 12, 2016 Gormley resigned from the Remai Modern board of directors.

In June 2016, the museum rebranded again as Remai Modern, with the museum's logo stylized as "rRemai mModern". Karlssonwilker was contracted by the museum for $90,000 to design the museum's logo, website, and other merchandise. Although the institution's rebranding saw "Art Gallery of Saskatchewan" omitted from its name, the museum remains formally incorporated as the Art Gallery of Saskatchewan Inc., under the province's Non-profit Corporations Act.
