Glenn Franklin Howerton III was born in Japan, the son of American parents Janice and Glenn Franklin Howerton Jr. His father was a fighter pilot. He spent his childhood moving back and forth between foreign countries and different parts of the United States; almost immediately after his birth, his family moved to Arizona and then New Mexico for a short while. When he was three years old, they moved to the English town of Felixstowe, Suffolk. They subsequently moved to Virginia, followed by South Korea, where they settled in Seoul. When he was 10 years old, his family moved to Alabama. After graduating from Jefferson Davis High School in Montgomery, Alabama, he spent two years at New World School of the Arts of Miami Dade College. He was part of Group 29 of the Juilliard School's Drama Division (1996-2000), where he graduated with a Bachelor of Fine Arts.
In 2002, Howerton starred as Corey Howard in the ill-fated That '80s Show. He went on to guest star on ER as Dr. Nick Cooper in 2003. He had small roles in the films Must Love Dogs (2005), Serenity (2005), Two Weeks (2006), and The Strangers (2008). He also appeared as a nurse in Crank (2006), and reprised the role in its 2009 sequel, Crank: High Voltage. Howerton is most notably involved in It's Always Sunny in Philadelphia (2005-) as one of the main cast, producer and director, and has also written numerous episodes. He planned to be executive producing on the comedy show Boldly Going Nowhere with his It's Always Sunny in Philadelphia co-creators, before the show was delayed. Howerton had a recurring voice role on The Cleveland Show as Ernie Krinklesac, as well as recurring roles on the Fox comedy series The Mindy Project and the FX dark comedy series Fargo. He starred in the 2013 comedy film Coffee Town. He also had a bit part as the gun running Dominic, in the 2016 Netflix Original Officer Downe, starring Kim Coates. He also starred in the 2018 NBC comedy A.P. Bio.
On September 8, 2009, Howerton married actress Jill Latiano, who guest starred on the It's Always Sunny in Philadelphia episode "The D.E.N.N.I.S. System" two months later. Their first son, Miles Robert, was born in 2011. The couple had a second son, Isley Ray, in August 2014.
Howerton has said that he follows a vegan diet "about 95% of the time".
