Balogun will spent the remainder of the campaign with the Sky Bet Championship side after agreeing to join the Latics on the transfer deadline day.
The centre-back failed to make a single appearance for Brighton in the Premier League before the move.
Linking up with Wigan, who are fighting to escape the drop from the Sky Bet Championship, could help him earn recognition at the international level again.
Last season, the Nigeria international featured in eight league games for Brighton and scored once.
“Our new recruits have arrived
😀👋 Welcome, Alex Dobre,
@jan_mlakar & @LeonBalogun,” reads a Tweet on Wigan’s official Twitter handle on Monday.
The 31-year-old will look to make his debut when Wigan host promotion hopefuls Preston North End on Saturday.
