Artur Razmikovich Grigorian (Armenian: Արթուր Գրիգորյան; born 20 October 1967) is a retired Armenian-Uzbek professional boxer.

[4] Grigorian won a silver medal at the 1991 World Amateur Boxing Championships and competed at the 1992 Summer Olympics in Barcelona.

On 23 July 1994, Grigorian defeated Turkish boxer Senturk Ozdemir by a fifth-round technical knockout and won the vacant German International lightweight title.

The title had recently been vacated by Oscar De La Hoya after he moved up to the light welterweight division.

Artur was just one more defense away from becoming the longest reigning lightweight champion, but ultimately lost his belt to Acelino Freitas by unanimous decision on 3 January 2004.

On 24 February 2009, at the age of 41, Artur came out of retirement for one more bout in which he won a six-round unanimous decision against Bulgarian Kirkor Kirkorov.
