Hoolahan is a Republic of Ireland under-21 international
The 22-year-old has signed a two-and-a-half year contract.
Livi player-boss Paul Lambert believes that he has captured one of the most exciting players in the Irish League.
"We watched him several times before the end of the Irish season and he lived up to all we had heard about him," Lambert told his club website.
"He is an exciting player and will bring us width and more attacking options.
"Wes will bring additional quality to a side that works hard and plays as a team, which is vital as we enter the second half of the season."
Lambert is anxious to improve his squad, currently struggling in the Scottish Premier League relegation zone.
Hoolahan played 29 times for Shelbourne last season, including Champions League qualifiers, scoring four goals.
And Shelbourne manager Pat Fenlon said: "He's not a player we want to lose, but Wes would have no problems coping with Scottish football. He is very skilful."
