Le convenienze ed inconvenienze teatrali (Conventions and Inconveniences of the Stage) is a dramma giocoso, or opera, in two acts by Gaetano Donizetti. The Italian libretto was written by Domenico Gilardoni, adapted from Antonio Simone Sografi's plays Le convenienze teatrali (1794) and Le inconvenienze teatrali (1800).
The title refers to the convenienze, which were the rules relating to the ranking of singers (primo, secondo, comprimario) in 19th-century Italian opera, and the number of scenes, arias etc. that they were entitled to expect.
The opera was originally a one act farsa based on Le convenienze teatrali; this version premiered at the Teatro Nuovo, Naples on November 21, 1827. Donizetti revised it and added recitatives and material from Le inconvenienze teatrali; this final version premiered at the Teatro Cannobiana, Milan on April 20, 1831.
