Marie François Oscar Bardi de Fourtou (3 January 1836 – 6 December 1897) was a French politician.

As minister of education, religion and the fine arts in the reconstructed cabinet of the duc de Broglie he had used his administrative powers to further clerical ends, and as minister of the interior in de Broglie's cabinet in 1877 he resumed the administrative methods of the Second French Empire.

In the general elections of that year he used the whole weight of officialdom to secure a majority for the Right, to support a clerical and reactionary programme.

He accompanied Marshal MacMahon in his tour through southern France, and the presidential manifesto of September, stating that the president would rely solely on the Senate should the elections prove unfavourable, was generally attributed to Fourtou.

In spite of these efforts the cabinet fell, and a commission was appointed to inquire into their unconstitutional abuse of power.

Failing to secure re-election to the Senate in 1885 he again entered the popular chamber as Legitimist candidate in 1889, but he took no further active part in politics.
