The San Nicolás Agreement (Spanish: Acuerdo de San Nicolás) was a pact signed on May 31, 1852 and subscribed by all but one of the 14 provinces of the United Provinces of the River Plate (the exception was Buenos Aires). The treaty consisted of 19 articles, and its goal was to set the bases for the national organization of the young Argentine state. It also served as precedent to the sanction of the Argentine Constitution of 1853.
The agreement named Justo José de Urquiza as provisional Supreme Director of the Argentine Confederation, established the application of the Pact of 1831, and set the gathering for a General Constitutional Congress in the city of Santa Fe.
