Đại hội quốc gia thứ tư tại Argos

The Fourth National Assembly at Argos (Greek: Δʹ Εθνοσυνέλευση Άργους) was a Greek convention which sat at Argos from 11 July to 6 August 1829, during the Greek War of Independence.

The Fourth National Assembly followed on from the Third National Assembly at Troezen (1827), which had adopted a new constitution and selected Ioannis Kapodistrias as Governor of Greece with extensive powers for a seven-year term. The Assembly counted 236 representatives from all over Greece (including territories, such as Crete or Macedonia, that were still under Ottoman control), for the first time elected via suffrage.

The Assembly adopted a series of reforms suggested by Kapodistrias, most notably:

the replacement of the Panellinion advisory council with a 27-member Senate

the adoption of the phoenix as the country's currency
