Cornelis (Cornelius) Columbanus Vrancx (Dendermonde, circa 1529/1530 – Ghent, 15 August 1615) was a Flemish writer of prose, poetic refrains and spotlied against the Reformed. He was the 60th abbot of St Peter's Abbey in Ghent from 1597 and wrote thirty-seven concise works. Cornelis Columbanus Vrancx is seen as the forerunner of the Flemish poet Adriaan Poirters.
