The midfielder has signed a three-year contract with the Premier League side after the two clubs agreed an undisclosed fee.
The 26-year-old arrived at the club's Beckenham training ground to meet with new manager Neil Warnock earlier today and undergo a medical.
McArthur joined Wigan from Scottish side Hamilton Academical in 2010.
