Pre-debut
 Siwon has one younger sister - Jiwon. His father is currently the CEO of Boryung Medicine, a pharmaceutical company. He graduated from Gu Jeong High School in February 2006. Siwon is a devout Protestant Christian, and has said in an interview that after his career, he would like to become a missionary.
Siwon was scouted by a talent agent from SM Entertainment when he was 16 as he was waiting for friends in front of his high school. The agent recommended him to audition for the company's Starlight Casting System. He auditioned without his parent's approval; his parents were notified only after he passed the auditions.

Although his parents allowed him to sign a contract with SM Entertainment, they did not give him any help because they wanted him to take responsibility for his actions. He later moved into dormitories with fellow trainees and was trained in areas of singing, acting, and dancing. He was featured in a music video of The Grace's Dana whilst he was being trained as a solo singer in 2003. A year after, Siwon made a brief appearance in short drama, Precious Family and again in 2005, KBS drama Eighteen, Twenty-Nine as young Kang Bong-man and played the supporting role of Park Sang-woo in drama Spring Waltz in 2006.

A few months before the debut of Super Junior 05, Siwon made his first official media appearance with band mate Han Geng as one of the runway models in a fashion show by Bum Suk. Siwon officially debut as part of 12-member rotaional project group Super Junior 05 on 6 November 2005 on SBS's music programme Popular Songs, performing their first single, "Twins (Knock Out)". Their debut album SuperJunior05 (Twins) was released a month later on 5 December 2005 and debuted at #3 on the monthly MIAK K-pop album charts.

In March 2006, SM Entertainment began to recruit new members for the next Super Junior generation. However, plans changed and the company declared a halt in forming future Super Junior generations. Following the addition of thirteenth member Kyuhyun, the group dropped the suffix "05" and became officially credited as Super Junior. The re-polished group's first CD single "U" was released on 7 June 2006, which was their most successful single until the release of "Sorry, Sorry" in March 2009. In the fall of 2007, the group released their second official album, Don't Don, which became Super Junior's best-selling album and Korea's second best-selling album of the year.
