Jacoba van Velde (10 May 1903, in The Hague – 7 September 1985, in Amsterdam) was a Dutch writer, translator, and dramaturge.
Her first novel, De grote zaal (The Great Hall), appeared in the literary journal Querido in 1953 and was translated into thirteen languages within ten years.
At age sixteen, she had already been associated with the company that would later be officially called Bouwmeester Revue for a few years as figurante and then in the dance ensemble.
Just after the war, she was a literary agent under the name Tonny Clerx, for the French work of the Irish author Samuel Beckett.
She translated plays by Samuel Beckett, Eugène Ionesco and Jean Genet from French to Dutch, among other things.
