Constantin Sebastian Colțescu (born 6 May 1977) is a Romanian football referee.

Colțescu was promoted to the Division A in 2003,[1] when he led the match between Oțelul Galați and Gloria Bistrița, on 28 November 2003.

He made his debut in the Intertoto Cup in a match between Zrinjski Mostar and Marsaxlokk on 27 July 2006.

On 8 December 2020, Colțescu was accused of racism during a UEFA Champions League match between Paris Saint-Germain and İstanbul Başakşehir, after referring to former player Pierre Webó as "the black one".

UEFA launched an investigation and subsequently cleared Colțescu of charges of racism and discriminatory conduct, but suspended him from refereeing for the remainder of the season for displaying "inappropriate behavior" in the match.
