Simon Nessman, born on November 6, 1989, in Courtenay, British Columbia, Canada, is a renowned Canadian model. He is the youngest of four children, born to Carolyn Ireland and Ron Nessman. His journey into modeling began unexpectedly in late 2006 when a friend of his sister sent pictures of him to talent scout Kelly Streit of Mode Models of Canada.

At that time, he was still attending high school at Georges P Vanier Secondary and did not pursue his modeling career until after graduation. He later moved to New York City to fully immerse himself in the modeling industry, where he stayed for the next five years.

Simon Nessman is best known as the face of Giorgio Armani. He has also featured in ad campaigns for prestigious brands such as Versace, D&G, Givenchy, Calvin Klein, Ralph Lauren, Lanvin, Yves Saint Laurent, Barneys, Gap, and John Galliano. His presence in the fashion world is marked by his appearances in Vogue, Details, Numéro, V Man, and L'Officiel Hommes.

He has walked the runway for Salvatore Ferragamo, Roberto Cavalli, Tommy Hilfiger, Emporio Armani, Viktor & Rolf, Lacoste, DSquared, Narciso Rodriguez, and Michael Kors.

In 2012, he became the face of the Giorgio Armani fragrance Acqua di Gio Essenza, a campaign shot and directed by Bruce Weber. He continued to feature in the 2014 print and video campaigns for the fragrance.

In addition to his modeling career, he appeared in the 2012 music video for Madonna's song "Girl Gone Wild," directed by fashion photographers Mert Alas and Marcus Piggott. From late 2010 to 2014, he starred in multiple print and film campaign advertisements for American fashion designer Michael Kors alongside Karmen Pedaru. He also appeared with British supermodel and actress Cara Delevingne in the John Hardy Spring/Summer 2015 campaign, shot by Sebastian Faena in Bali.

His achievements in the modeling industry are notable. In 2011, he was ranked the second most successful male model in the world by models.com. In 2013, Forbes ranked him third on their list of The World's Highest-Paid Male Models, behind David Gandy and Sean O'Pry.

Outside of modeling, he is passionate about sports. He was an avid player in his school's basketball and rugby teams and received offers from both The University of The Fraser Valley and Quest University in British Columbia. In 2013, he returned to Canada to pursue his college basketball career at Quest University in Squamish, where he graduated in May 2017 with a Bachelor of Arts and Science.
