The Wajak crania (also Wadjak, following the Dutch spelling of the toponym) are two fossil human skulls discovered near Wajak, a village in Tulungagung Regency, East Java, Indonesia (then Dutch East Indies) in 1888/90. The first was found on 24 October 1888 by mining engineer B.D. van Rietschoten who sent it to paleontologist Eugène Dubois who subsequently found the second skull in September 1890.
