Sean Monaghan, also known as "Seanie," is a retired American professional boxer of Irish descent. He competed in the light-heavyweight division, which ranges between 168-175 pounds, during his more than eight-year career that ran from 2010 to 2019.

The 5'11" boxer was born on May 21, 1981, in Long Beach, New York, and had a reach of 72.5 inches. During his career, Monaghan won 29 fights, lost three, drew none, and recorded no no-contests.

Monaghan's style was orthodox, which means he typically led with his left foot and jabbed with his left hand while his right hand was the power hand.

The boxer had a reputation for explosive power, having recorded 17 of his 29 wins by knockout.

Monaghan made his professional debut in his hometown of New York City against Simeon Trigueno in 2010. He took out Trigueno in the first round with a TKO victory, which marked the beginning of his illustrious career.

However, Monaghan's 28-fight winning streak came to an end in July 2017 when he fought Marcus Browne. Browne defeated Monaghan via TKO in the second round, marking the first loss of Monaghan's professional career.

In his 32 professional bouts, Monaghan never won a title or had any title defenses. However, he fought against noteworthy opponents such as Browne and Sullivan Barrera, who defeated Monaghan via unanimous decision in their ten-round match in 2018.

Monaghan's last professional fight occurred on March 9, 2019, against British boxer Callum Johnson. The non-title bout ended in the third round when Johnson defeated Monaghan via TKO. The loss marked the final bout of Monaghan's career, as he retired with a record of 29-3.

Although he did not win any titles, Monaghan earned respect in the boxing community for being a formidable and entertaining fighter. His knockout power and fighting style earned him the nickname "Seanie" and a loyal fanbase.
