San Marino, officially the Republic of San Marino, is a landlocked country in Southern Europe, completely surrounded by Italy. Located on the northeastern slopes of the Apennine Mountains, it is the larger of two microstates within the Italian Peninsula, the other being Vatican City. San Marino is the fifth-smallest country in the world, with a land area of just over 61 square kilometres (24 sq mi) and a population of 34,042 as of 2025 which in 2026 dropped to 33,559. Its capital, the City of San Marino, sits atop Monte Titano, while its largest settlement is Dogana, in the municipality of Serravalle. San Marino claims to have been founded in AD 301 and to be the oldest extant sovereign state, and the oldest constitutional republic. It is named after Saint Marinus, a legendary stonemason from the Roman island of Rab (in present-day Croatia), who is said to have fled persecution under Emperor Diocletian to have established a monastic community on Monte Titano, where he built a small chapel.

San Marino, officially the Republic of San Marino, is a landlocked country in Southern Europe, completely surrounded by Italy. Located on the northeastern slopes of the Apennine Mountains, it is the larger of two microstates within the Italian Peninsula, the other being Vatican City. San Marino is the fifth-smallest country in the world, with a land area of just over 61 square kilometres (24 sq mi) and a population of 34,042 as of 2025 which in 2026 dropped to 33,559. Its capital, the City of San Marino, sits atop Monte Titano, while its largest settlement is Dogana, in the municipality of Serravalle. San Marino claims to have been founded in AD 301 and to be the oldest extant sovereign state, and the oldest constitutional republic. It is named after Saint Marinus, a legendary stonemason from the Roman island of Rab (in present-day Croatia), who is said to have fled persecution under Emperor Diocletian to have established a monastic community on Monte Titano, where he built a small chapel. The country has a rare constitutional structure: the Grand and General Council, a democratically elected legislature, selects two heads of state, the Captains Regent, every six months. They are chosen from opposing political parties, and serve concurrently with equal powers and preside over several institutions of state, including the Grand and General Council. Only the Federal Council of Switzerland follows this same structure, except with some modifications due to its immensely larger size.
San Marino is a member of the Council of Europe and uses the euro as its official currency, but is not part of the European Union. The official language is Italian, although the traditional regiolect is Sammarinese, a dialect of Romagnol. Its economy is based on finance, industry, services, retail, and tourism, and it ranks among the wealthiest countries in the world by GDP (PPP) per capita. It hosts the Parliamentary Assembly of the Mediterranean. San Marino was also the first currently-existing state to abolish the death penalty (in 1865), although it had not actually been used since the 1400s. In 2025 San Marino was ranked 29th on the Human Development Index.
