Common Lisp can be used as a functional language, or imperative, or extremely advanced OO (see CLOS).
There are lots of different Lisp's though. Clojure is the most popular one that runs on the JVM and idiomatic Clojure is generally pretty functional although it calls out to lots of Java which is OO.
