Andrew George Blair PC KC (March 7, 1844 – January 25, 1907) was a Canadian politician in New Brunswick, Canada.

Blair's government built a three-quarters of a mile long bridge across the Saint John River, linking Fredericton with villages and factories, notably that of Boss Gibson, on the other side of the river, in spite of opposition by the federal government, which maintained that it was beyond provincial power to do so.

The Liberal government almost lost the 1889 election but was able to stay in power with the support of independent Members of the Legislative Assembly (MLAs).

Blair lost his own seat in the 1892 election, due to Protestant opposition to his policy of accommodating Acadians and other Catholics.

He was sworn in as Minister of Railways and Canals on 13 July 1896,[1] entered the House of Commons of Canada in an August 1896 by-election for Sunbury and Queens riding,[1] and was re-elected in the 1900 election.

[3] He further stated that other Ministers had been allowed to discuss with Grand Trunk officers plans for the transcontinental without informing him.

[1] Blair died on January 25, 1907, of a heart attack during a dinner party in Fredericton, New Brunswick.
