The Congress of Angostura is known as the Constituent Assembly convened in 1819 by the Venezuelan liberator, Simón Bolívar. It met in the city of Santo Tomás de Angostura, in what is now Ciudad Bolívar, east of the Bolivarian Republic of Venezuela.
The Congress of Angostura was made up of 30 deputies who belonged to 7 of the former provinces of the Captaincy General of Venezuela. His objective was to unite Venezuela and New Granada into a single nation, called Colombia.
