While executing a visual approach to [Runway] 1 Right backed up with the RNAV gps we saw what at first we assumed was a bird.  Once it was about to pass directly over the aircraft it was clearly a drone; we were passing through 4;100 feet MSL and descending I would estimate it was less than 100 feet above us and directly overhead.  We reported it to the Tower and continued without incident.
On final approach into LAS we observed an object/possible drone around 4;000 feet MSL. The object passed about 100 feet directly overhead. We reported the event to Tower and landed uneventfully.
Air carrier flight crew came within 100 feet of a drone while on final approach at LAS airport.
