The open-top bus tour will start at the top of White Horse Lane at 1pm, with the winning players and the trophy.
It will then turn into Park Road and travel down Holmesdale Road.
The parade is free for everyone to attend and is expected to last about 45 minutes.
This will be followed by a ‘party on the pitch’ at Selhurst Park.
Croydon Council is waiving the costs of the street closures and street cleaning for the parade.
Palace won the FA Cup following their 1-0 win against Manchester City in a nail-biting game at Wembley last weekend.
It is the football club’s first major trophy in their 164-year history.
