Johannes Crabbe (c. 1420 – 1 November 1488) was abbot of Ten Duinen Abbey in present-day Belgium, an imperial counsellor and bibliophile.
He made a career within the Catholic church, entering the Cistercian Order and joining the Ten Duinen Abbey.
The case was settled when James of Portugal died, and Isabella accepted Crabbe as abbot in exchange for a large sum of money.
Though thus initially incurring large debts on behalf of the abbey, he managed in a short time to bring its finances into balance and reinvigorated the religious life there.
He was also employed as a valued counsellor to Mary of Burgundy and Emperor Maximilian I, and from 1477 functioned as the president of the Imperial council several years.
