Dănuţ Marcu (born 11 January 1952) is a Romanian mathematician and computer scientist, who received his Ph.D. from the University of Bucharest in 1981. He claimed to have authored more than 400 scientific papers.
Marcu was frequently accused of plagiarism. The editors of Studia Universitatis Babeş-Bolyai, Informatica decided to ban Marcu from their journal for this reason, as did the editors of 4OR and the editors of Geombinatorics. The editors of Geometriae Dedicata state that they suspect Marcu of plagiarism, as he submitted a manuscript which is "more-or-less word for word the same" as a paper by Bernt Lindström. Jerrold W. Grossman, Sanpei Kageyama, Martin R. Pettet, and anonymous reviewers have accused Marcu of plagiarism in MathSciNet reviews. According to the managing editors of Menemui Matematik, Marcu's paper in that journal is a well known result in graph theory, and the paper "should not have been published".

it is his reputation as a prolific plagiariser of academic papers which is the source of his notoriety in the academic and publishing communities.

This paper quotes Bouyssou, Martello & Plastria (2006) concerning Marcu, including the quote from an unnamed "well-known mathematician" that "Marcu is a notorious plagiarist".

Individual cases of academic plagiarism continue to attract significant media attention. Mathematician and computer scientist Danut Marcu claimed to have published over 383 original papers in various scientific publications. A number of his recent papers were shown to be exact copies of papers published earlier by other authors..

Another example of a habitual plagiarizer is found in the field of management sciences, where author Dănuț Marcu published three plagiarized papers in Studia Universitatis Babes-Bolyai Series Informatica during 2002–2003 and subsequently tried to publish another “lifted” piece in the Quarterly Journal of Operations Research ... Marcu was subsequently “outed” and banned from publishing his work in the above journals. The plagiarized rejected piece from 4OR was later published in another journal.[permanent dead link]
