Another way: (first (keep identity coll)). user=> (first (keep identity [nil false 1 2 3])) false user=> (first (keep identity [nil 1 2 3])) 1 user=> (first (keep identity [nil nil nil])) nil user=> (first (keep identity [])) nil If your collection does never contain false, you can simply use (some identity coll).
