Armagh will face Ulster rivals Tyrone next weekend after Jamie Clarke's double secured victory in the All-Ireland second round qualifier replay.
Wicklow moved into an early lead before Clarke netted in the 19th minute and the Orchard men held a 1-5 to 0-6 advantage at half-time in Aughrim.
The game remained tight until the Crossmaglen forward struck again with a shot past keeper John Flynn.
Clarke hit a superb point as Armagh moved clear for a comfortable win.
Armagh fired over the opening points through Micheal O'Rourke and Clarke but Paul Earls and Tony Hannon each hit two to put Wicklow 0-4 to 0-2 ahead.
Malachy Mackin's flick set up Clarke for his opening goal, scoring at the second attempt after his initial effort was blocked by Flynn.
Mackin also created the second goal with another flick, with Clarke again firing beyond Flynn.
Clarke completed a fine display with an excellent point, but it was his goals which proved the difference between the sides.
