"(WAPOOSH) Top of the mornin' to ya, laddies! My name is Jacksepticeye, and welcome (back) to [game name]!"

- Jacksepticeye’s classic intro

Seán William McLoughlin (born: February 7, 1990), better known online as jacksepticeye (or simply Jack), is an Irish YouTuber, video game commentator, occasional vlogger, voice actor, and founder of the clothes company CLOAK (along with Markiplier). He is known for his energy, distinct accent, loud commentary and sometimes gentle nature and (now former) signature green hair (which he dyed for charity alongside Markiplier). His channel is the 113th most subscribed channel on YouTube, and also the most subscribed channel in Ireland.

In a video released on July 2, 2020, Seán went on a month-long break due to mental health and the situations going on currently with YouTube and Twitch while explaining why he doesn't want to upload daily content because he needs to, he is taking a month off because he doesn't want to make YouTube videos at this time. Seán returned to his YouTube channel on August 11, 2020 with a livestream announcing his return to uploading content following his break.

History
Jack created his YouTube channel on February 24th 2007, although he didn't start making his own videos until November 2012, his very first upload being a Metal Gear Solid 4 impression on Solid Snake. According to Jack in a 2017 video, he originally wanted the channel to be dedicated to impressions.

Whilst playing Battlefield 3, Jack searched for tips online and came across LevelCapGaming. Jack was also a fanboy of Markiplier and PewDiePie, becoming part of his inspiration to start his own channel. Lacking friendships and living in a remote area, he turned to YouTube so he could create an online community, despite being pressed for time to make videos since he was also studying for exams in college. In September 2013, he entered PewDiePie's shout out competition and was one of several channels who won, where he went from 2,000 to 15,000 subscribers and pounced upon the opportunity to improve. Mark noticed Jack by writing on Twitter that he had entertaining videos, resulting in their first ever collaboration being "Gmod Sandbox w/ Markiplier | DON'T WORRY....WE'RE SCIENTISTS."

From 2012 until 2014 Jack lived beside his parents in a cabin, causing issues with his internet affecting his uploads. He had to use a camera as his microphone and attempted to hide his Irish accent by pretending to be American for fear of being made fun of.

In 2014, he moved to an apartment in Athlone for better internet access. He graduated from college that same year and earned a degree in hotel management. In 2016, Jack hired Robin as his first editor. For the first time in five years in October 2017, there were no scheduled uploads for a week due to Jack touring with the Game Grumps.

Jack kick started 2018 with the motto, Positive Mental Attitude ('PMA' for short), which turned into a merchandise line released in August 2018. Between July and October 2018 he took an extended break to Los Angeles. His previous upload schedule was two videos per day seven days a week, although has since decreased beginning on July 20th, 2018; during August 2019 he resumed his former schedule.

While his main focus is on game plays of a variety of different genres, from indie to horror to upcoming releases, he occasionally does vlogs and sketch comedy. He is known for his energetic and caring personality, but tones down to seriousness when something needs to be talked about. He has shown his appreciation for his fanbase multiple times, such as making a subscriber milestone video thanking them.
