(actual name: Hieronim Konarski; 30 September 1700 – 3 August 1773) was a Polish pedagogue, educational reformer, political writer, poet, dramatist, Piarist priest and precursor of the Enlightenment in the Polish–Lithuanian Commonwealth.

In 1740 he founded the Collegium Nobilium, an elite Warsaw school for sons of the gentry (szlachta).

Stanisław August caused a medal to be struck in Konarski's honour, with his likeness and the motto, from Horace, Sapere auso ("Dare to know!").

Konarski argued very strongly that the right of veto that had traditionally been exercised by the Polish Nobility was not law but a custom.

[1] In his most important work, the four-part O skutecznym rad sposobie albo o utrzymywaniu ordynaryinych seymów (On an effective way of councils or on the conduct of ordinary sejms, 1760-1763), he unveiled a far-reaching reform program for the Polish parliamentary system and political reorganization of the Commonwealth's central government, which included aiding the monarch with a permanent governing council.
