The Allegory of Good and Bad Government is a series of three fresco panels painted by Ambrogio Lorenzetti between February 1338 and May 1339.
The paintings are located in Siena's Palazzo Pubblico—specifically in the Sala dei Nove ("Salon of Nine"), the council hall of the Republic of Siena's nine executive magistrates, elected officials who performed executive functions (and judicial ones in secular matters).
The paintings have been construed as being "designed to remind the Nine [magistrates] of just how much was at stake as they made their decisions".

Considered Lorenzetti's "undisputed masterpiece", the series consists of six different scenes (the titles are all modern conveniences):
Allegory of Good Government
Allegory of Bad Government
Effects of Bad Government in the City
Effects of Bad Government in the Country
Effects of Good Government in the City
Effects of Good Government in the Country
