Narrative:
Upon landing at ZZZ and taxiing to the gate; one of the company ramp personnel discovered a panel missing from the captain's side lower wing; just aft of the leading edge flaps. I went down to the ramp to take a look and verified that the panel and all but one of the fasteners were missing. The lone fastener was near the center of the aft set of fasteners. We grounded the aircraft and stepped to another. During my walkaround in ZZZ1; I cannot remember the panel to be missing. My standard flow walks me out to the wingtip along the aft end of the wing and back to the fuselage down the leading edge. I'm sure I would have seen a missing panel. No other damage was done on the aircraft upon my further inspection at ZZZ.
