On approach to Runway XX at ZZZ. Pilot flying had just called for landing gear extension. We were just outside ZZZZZ intersection at exactly 2;500 ft MSL descending; a drone went right under us; illuminated by the landing light. I estimate that the drone was no more than 20 feet below our altitude; directly in-line with our flight path horizontally. The first officer caught a glimpse of it; I saw it for a fraction of a second. I would not have had time to avoid the drone. The drone was white; with something red; either paint or a dim light. The drone was reported to ZZZ tower.
Air carrier flight crew was on approach to a Class B airport and came within 20 feet of a UAV while on final approach.
