I came across this on the outside of my dining room window. It's the size of a grape. Is it a Praying Mantis cocoon? And has it hatched yet? I don't want to disrupt it, whatever it is...

That does appear to be praying mantis handiwork. Not a cocoon but an egg sack. They will hatch in spring and lower themselves on filaments. There could be 200-600 eggs in there. The young are cannibalistic so usually 6-12 survive. That’s a pretty cool find.
@Bearsfan67 I think I'll just leave it alone. It's attached to the screen frame, which I have to take out in order to get to the window itself so I'll just let it be 🙂
