Aircraft X was turned and cleared for the ILS Approach. After the clearance was given; the pilot advised he had the runway in sight. The developmental questioned the pilot and asked if he also had a different airport in sight at 12 o'clock and 5 miles. The pilot advised he had the wrong airport in sight and that he would continue with the ILS approach.  We have had several instances within the past month where pilots have tried to land on the closed runway at the wrong airport when they have been cleared for approach into the nearby airport; even if the aircraft is on an instrument approach. The runway at the wrong airport has been closed for decades but pilots still confuse it for the runway at the nearby airport. In addition to controllers properly pointing out the airports in close proximity; it may be beneficial for the airport to put on their ATIS not to confuse the closed runway with their runway. Also depict the closed runway on the ILS approach chart since many pilots seem to quit flying their instruments as soon as they see a runway.
GSP Approach Controller reported that pilots often confuse Runway 35 at GYH; a closed runway 6 NM away; for Runway 1 at GMU.
