Katarzyna Tomicka (c.1510 – 1557) was a Polish noblewoman, known as the opponent of her sister-in-law queen Barbara Radziwiłł.

Katarzyna was born around 1510 in an unknown location, the third daughter of podkomorzy of Kalisz, Jan Tomicki h. Łodzia and sister-aunt of the Court Marshal and Bishop of Kraków, Piotr Tomicki h. Łodzia. She died in 1557; it is not known exactly where she died.

Her sons initiated the so-called "Calvinist lineage" of the Radziwiłł family. The male line expired in 1669.
