On left base to a visual approach; to Runway 31; we had a near miss with a drone at 3700 feet MSL. I first saw the drone at our left 10 o'clock; and approximately 50 to 100 ft away (hard to tell without knowing the actual size of the thing). It had a white body with blue highlights and black propeller guards. Not sure if it had 4 or 6 props. I immediately notified Approach. After landing; Ground gave us a phone number to make a report.
Air carrier Captain flying the Runway 31 visual approach at BNA reported a UAV near miss at 3;700 feet.
