Using a large pitcher, pour orange juice, peach juice and ginger ale, stir to combine.
Add in ginger "juice" 2 tablespoons at a time until desired flavor. For light flavor, about 1/4 c (4 T) and then more to your liking. Stir well and chill.
Muddle or mash raspberries in a bowl and add to punch before serving.
