Kortajarena was born in Bilbao, Biscay, Basque Country, Spain. He was discovered in September 2003 while vacationing in Barcelona and accompanying a friend who was invited to attend a fashion show. While there, a booker noticed him and persuaded him to give the fashion world a go. His first professional experience was in a Madrid Fashion Week show for Roberto Verino. He left Bilbao, his hometown, and ventured into the fashion industry in Paris. In 2004, at the age of 18, Kortajarena became the face of Just Cavalli for Roberto Cavalli's spring campaign which quickly jet started his career. He made his international fashion show debut at the fallMilan and Paris fashion weeks for Emporio Armani and John Galliano. Two months later, in New York, Steven Meisel photographed him for Versace. Kortajarena's other runway credentials include walking for Bottega Veneta, Dolce & Gabbana, Salvatore Ferragamo, Carolina Herrera, Giorgio Armani, John Galliano, and Chanel in Milan and Paris. Kortajarena appeared in a commercial for the sugar-free Fanta Z "Mediterraneo", a TV ad in 2005 which poked fun at the departed Fanta Lite. Its content, though, quickly drew complaints in Britain and it eventually became restricted to the post-9 PM broadcasts.
2007–2009
In 2007, Kortajarena signed with Guess and renewed his contract again in 2008. With new campaigns on the stands, Terry Richardson photographed Kortajarena for Tom Ford alongside Noah Mills and became the label’s signature male model for the next consecutive seasons. He was featured on the cover of the spring/summer 2008 issue of L'Officiel Hommes magazine, devoting him 200 pages, with the cover title reading "200 Pages of Fashion with Jon Kortajarena". It was the first time a male model had achieved this and consequently it became a reference in the industry; other models to follow such honor were Andres Velencoso and Arthur Sales. For the 2009 spring men’s wear and eyewear advertising campaigns Jon was art directed and photographed, for the first time, by Tom Ford himself. On 26 June 2009, Forbes published its list of The World's 10 Most Successful Male Models ranking Kortajarena in 8th place. In November Kortajarena was named by German GQ as Model of the Year. Spain's Marie Claire awards "Prix de la Moda" awarded him Best Spanish Model for 2009.

In 2011 he was selected as one of the models to star in Lacoste's $66 million new advertising concept under the new tagline, "Unconventional Chic". The ads were shot by Mert and Marcus showing models wearing the iconic white Lacostepolo shirts worn over eveningwear. He fronted the cover of the March 2011 issue of Vogue Spain alongside Anja Rubik and compatriot Andres Velencoso.
