Solesmes Abbey or St. Peter's Abbey, Solesmes(Abbaye Saint-Pierre de Solesmes) is a Benedictinemonastery in Solesmes (Sarthe, France), famous as the source of the restoration of Benedictine monastic life in the country under Dom Prosper Guéranger after the French Revolution.

Solesmes Abbey was founded in 1010 by Geoffrey, Lord of Sable, who donated the monastery and its farm to the Benedictine monks of the Saint-Pierre de la Couture Abbey, "for the redemption of his soul and those of his parents, or those who went before him and those who come after him".  The church was dedicated on 12 October, sometime between 1006 and 1015. The Abbey celebrated a Jubilee Year from 11 October 2010 to 12 October 2010. Solesmes was sacked and burned during the Hundred Years' War but was later restored.

The rebuilding of the church started towards the end of the fifteenth century. Prior Philibert de la Croix changed its plan from the basilica form to a Latin cross. His successor, Jean Bougler (1505-1556), completed the restoration of the church, added the tower, and rebuilt the cloisters, sacristy, and library. Under his direction two famous groups of statuary, known as the "Saints of Solesmes", were set up in the church. In the sixteenth century these masterpieces were in danger of being destroyed by the Huguenots and other Iconoclasts, but the monks saved them by erecting barricades.

From the 17th century on, Solesmes Abbey underwent a slow decline under a series of commendatory priors. The superior was a layman who received part of the monastery's income without living there. However, in 1664, the monastery was aggregated to the St. Maur Congregation and a stricter monastic observance was resumed.

Following the French Revolution, the newly formed National Constituent Assembly prohibited all religious vows on 13 February 1790. At Solesmes one of the seven monks (the sub-prior) broke his vows to become a constitutional priest and soldier of the Republic. At the beginning of 1791, the monks began to leave the monastery, and those who wished to remain there were imprisoned or deported to the Island of Jersey.  One of them, Dom Pierre Papion, hid in order to celebrate secret masses across the region. After signing the Concordat, he became chaplain of the hospice de Sablé. Solesmes, whose occupants had been forced out in March 1791, was then commandeered as the country residence of a certain Henri Lenoir Chantelou and its archives were burned in a "civic" bonfire on 14 July 1794. The church was reopened at the time of the Concordat and the Lenoir de Chantelou family were given statues by Napoleon himself so that those at Mans were not removed.

In 1825, government property administrators sold the monastic buildings and 145 acres with its farms.
