• North and East: Loreto Region
• South: Huánuco Region
• West: La Libertad and Amazonas regions

The territory of San Martín can be divided into four morphological zones:

• the west, near the eastern side of the Andean Plateau, with a rough topography and many ravines;
• the zone of the wide valleys, with stepped terraces formed by the Huallaga River and its affluents, where population is engaged mainly in cattle and agriculture;
• the southwest zone, with a relief coming down from the Cordillera Azul, with low elevation, where is an impressive canyon known as Cajón de Sión, which finishes in the Cayumba rapids;
• a small lower-lying jungle zone with areas easily flooded and with almost no hills.

The Huallaga River is one of the most important rivers in the region. It forms, together with its tributaries a hydrographical system which drains all of the region's territory. The Pongo de Aguirre is an important canyon formed by the Huallaga going through the Andean hills.

In San Martín, Conservation International Peru lists an office in Rioja and leads the Alto Mayo Protected Forest Conservation Initiative in the Alto Mayo Protection Forest.^[1][2]

Tupac Yupanqui entered and subdued the Inca dominion, the province of Moyobamba, known back then by its native name, Muyupampa. In 1539, Spaniard Alonso de Alvarado reached the Mayo River and founded a city he named Santiago de los Valles de Moyobamba, which later became the capital of Maynas. Another important personality was Priest Manuel Sobreviela who, between 1787 and 1790, accomplished traveling across the Huallaga River and subsequently published a map named "Planning for the course of the Huallaga and Ucayali Rivers and for the Pampa del Sacramento".

On August 19, 1821, Moyobamba was the first Peruvian city in declaring its independence.

The construction of a highway in recent years has increased the exchange of different products, benefitting the economy of this region.
