Austria–Uruguay relations are the relations between Austria and Uruguay. Diplomatic relations between both countries exist since the times of the Austro-Hungarian Empire: in 1870, Baron Anton von Petz celebrated a Treaty of Friendship, Trade and Navigation between both countries.
The Austrian Ambassador in Buenos Aires is concurrent to Uruguay; Austria has an honorary consulate in Montevideo. Uruguay has an embassy in Vienna and a consulate in Salzburg.
There is also a small but significant group of people with Austrian descent in Uruguay, including some former members of the Austrian nobility.
Since 2009 there is a Social Security Agreement between both countries.
