The 6-foot-3, 305-pound Brown is the fourth commitment for the Demon Deacons in this recruiting cycle.
"I'm very relieved to be committed to Wake Forest," said Brown, who chose the Demon Deacons over offers from South Carolina, Colorado State and East Carolina. "That's where I wanted to be since the beginning, but I just wanted to talk it through with God and my family.
"Wake Forest made me feel wanted. They showed major love and the coaches recruited me hard. I like their culture, the direction the program is going and the fan support."
The Saluda standout is hoping to make an early impact.
"They've told me that if I come in and work really hard that playing time and everything else will take care of itself," Brown said.
Brown has already developed a strong relationship with defensive line coach Dave Cohen.
"Since they offered, we have always stayed in contact," Brown said. "I like how he has a strong relationship with all his defensive linemen. He was also honest with me about everything.
"He was there from beginning to the end. He said he would take care of me. He said he would look after me like a son and that I just needed to do my part."
He is looking forward to playing for head coach Dave Clawson.
"I'm excited and ready to play," Brown said. "He's a relaxed, but also competitive. I love that he's a good person and straightforward with people, too."
Brown joins Hope Mills (N.C.) South View offensive tackle Mike Edwards, McClellanville (S.C.) Oceanside Collegiate quarterback Sam Hartman and Florence (S.C.) Wilson safety Zion Keith in Wake Forest's 2018 recruiting class.
