Abraham a Sancta Clara (born Johann Ulrich Megerle; 2 July 1644 – 1 December 1709) was an Augustinian friar.

Sancta Clara was born Johann Ulrich Megerle, in Kreenheinstetten, Germany on 2 July 1644.

[2] In 1662, Abraham a Sancta Clara joined the Catholic religious order of Discalced Augustinians, and assumed the name by which he is known.

[1][3] The people flocked to hear him, attracted by the force and simplicity of his language, the grotesqueness of his humour, and the impartial severity with which he lashed the follies of all social classes.

[3] In his published writings, he displayed many of the same qualities as in the pulpit, shown best through the most notable specimen of his style, his didactic novel entitled Judas der Erzschelm (4 vols., Salzburg, 1686–1695).
