1335 Demoulina, provisional designation 1934 RE, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. Discovered by Karl Reinmuth at Heidelberg Observatory in 1934, the asteroid was named after Prof. Demoulin, a Belgian astronomer at Ghent University. It has a slower-than average spin rate of nearly 75 hours.
