Mason Wilder is a fictional character on The Young and the Restless, portrayed by Lamon Archey from 2012-2014.
Mason Wilder first arrives at Newman Enterprises for his interview and is mistaken by Phyllis Summers for an investor named Matt Merrick. He eventually reveals that he is Sarge's nephew and Jack Abbott hires him as his new assistant. Mason begins to secretly give Newman's original owner, Victor Newman information on the inter-workings at Newman. Mason meets Victor where he reveals that he has degrees in economics and international business and that he views Jack as a spoiled rich kid that had everything handed to him where as Victor earned everything on his own and Mason wants to learn from Victor. Mason agrees to give Victor the information he needs to retake control of his company in return for a better position once Victor is in charge again. However after becoming addicted to his painkiller medication after having back surgery, Jack stepped down and gave Adam Newman the position as owner of Newman. Adam then hired Sharon Newman the position that had originally been ran by Phyllis when Jack was in charge after she stepped down. Victor decided to have Mason switch Sharon's medication for her bipolar disorder with placebos. But Mason couldn't go through the plan as he was constantly being interrupted by Adam and Sharon and also had a change of heart as well, seeing that Adam was doing absolutely fine as CEO. But Victor refused to give up and during a meeting with Mason at the Genoa City Athletic Club, Adam spotted them and immediately figured it out what was happening. Because of his betrayal, Adam fired Mason. Mason was left jobless for awhile until Jack called him and asked to him to model for Jabot Cosmetic's newly introduced fashion line, modeling along with Summer Newman.
Mason is later seen working with Hilary Curtis as well as being in a relationship with her. Hilary and Mason are working together to plot against Neil Winters for the death of her mom, Rose Turner. Hilary suggests that Mason try befriending Devon Hamilton after he inherits $2.45 billion from Katherine Chancellor's will to get information, and possibly some of his fortune.
