Amanda,

This plant is a type of Sumac. There are 250 species in this genus (Rhus). I am not sure exactly which of those can claim this particular plant. Some of the species in this genus can be poisonous like Rhus toxicodendron (Poison Ivy) or Rhus vernix (Poison Sumac) while others are used as a cooking spice. You might want to take a leaf to your local garden center or extension service to make a positive id.
