Narrative:

We were approaching ZZZ intercepting the localizer for the ILS. ATC had descended us to 4;300 ft.; and cleared us for the approach. I had stayed at 4;300 ft. Since it was well below the glideslope. As we leveled out on the localizer; I had seen what looked like a larger bird at roughly the same altitude and within 300 ft. Of the localizer centerline. We neared the object and it turned out to be a glider; I disconnected the autopilot and executed a descending left turn to avoid the glider. After passing it; we determined that it was approximately 200 ft. To the side of us and about 100 ft. Above us after maneuvering. If we had not maneuvered; it would have been a lot closer. After we stabilized the aircraft; we were able to re-join the ILS and conduct a stabilized approach. We quered the tower; and said that he had contacted the glider field to report the incident. Cause: the glider was not talking to ATC; and had no transponder or adsb; so it was not showing up on our equipment nor ATC's. The glider was flying along the localizer center line at roughly the same altitude that ATC had been clearing aircraft for the approach. Suggestions: in the company pages; it does list out the location of where glider activity takes place at this airport. Make sure that you read and under stand the company pages and pay extra vigilance when approaching similar airports.
