Yes, it's called outline-minor-mode ;-)
For Elisp, I additionally use:

(add-hook 'outline-minor-mode-hook
          (lambda ()
            (when (and outline-minor-mode (derived-mode-p 'emacs-lisp-mode))
              (hide-sublevels 1000))))

which starts outline-minor-mode by hiding all the bodies of functions.
I also use `reveal-mode' which automatically unhides the bodies when you
try to move the cursor into them (so you don't need to remember the key
sequences to use for opening/closing elements).
