San Marino participated in the Eurovision Song Contest 2012, held in Baku, Azerbaijan. The Sammarinese national broadcaster Radiotelevisione della Repubblica di San Marino (SMRTV) internally selected Valentina Monetta with "The Social Network Song" to represent the nation in the contest. SMRTV had initially proposed a different version of the song, titled "Facebook Uh, Oh, Oh", but was instructed to modify or replace the entry due to concerns relating to commercial messaging. The entry was promoted through the creation of a music video, a promotional tour throughout Europe and interviews to the press in the lead up to the Eurovision Song Contest 2012. San Marino performed 11th in the first semi-final, held on 22 May 2012, and placed 14th, receiving 31 points and failing to qualify for the grand final. This marked their best placing in the contest to this point.

The Eurovision Song Contest 2012 was the 57th edition of the Eurovision Song Contest. It took place in Baku, Azerbaijan, following the country's victory at the 2011 contest with the song "Running Scared" by Ell and Nikki. It was the first time Azerbaijan hosted the contest – only four years after the country made its debut. Organised by the European Broadcasting Union (EBU) and host broadcaster İctimai Television (İTV), the contest was held at the Baku Crystal Hall, and consisted of two semi-finals on 22 and 24 May, and a final on 26 May 2012. The three live shows were presented by Azerbaijani television presenter Leyla Aliyeva, newsreader Nargiz Birk-Petersen and singer Eldar Gasimov, the latter of whom was one of the previous edition's winners.
