The microstate of San Marino joined the list of Eurovision countries in 2008. They made their debut with Miodio performing Complice. The country placed last in their semi-final, leading to a withdrawal from the next two contests.
San Marino returned in 2011 with Senit, again failing to qualify. The country has failed to qualify until 2014. Valentina Monetta, making her third consecutive participation, took San Marino out of the semi-final for the first time. This makes her the first singer to participate in three consecutive contests since Udo Jürgens, who competed in 1964, 1965 and 1966. However, Monetta broke a "prophecy" of winning at least once in three consecutive performances. They qualified for the second time in 2019, again, with a returning participant in Serhat Hacıpaşalıoğlu.
Former Junior Eurovision participants for San Marino Michele Perniola and Anita Simoncini represented the country in 2015. Monetta returned to the Eurovision stage in 2017 with Jimmie Wilson, scoring her worst result yet (last in the semi-final).
San Marino primarily votes with juries, as they do not have a sufficient independent televoting system (they share Italy's phone network).
