Narrative: Operating ZZZ-ZZZ1 parked at Gate XX we had run the before start checklist all the way through and were ready to push. I verified the ground crew was ready for brake release; released the parking brake and asked the First Officer to call for push. The First Officer called Ramp requesting to push; Ramp cleared us to push giving way to the airplane parking at Gate XY. I relayed these instructions to the ground crew. We didn't move and then the ground crew told me to set the parking brake; which I did. I saw a group of rampers coming out of the terminal looking towards our left wing. I checked to see what they were looking at and then saw that the winglet of the plane parking at Gate XY had hit our aileron. I asked the First Officer to call Ops and get the jet ridge brought back to the plane while I called Dispatch and Maintenance.  Once the cabin door was reopened and the gate agent was aware of what was going on; we deplaned the passengers.Wing walkers should look at wingtips to verify clearance. Verify there is enough space for our aircraft to park at [Gate] XY with a larger aircraft parked at [Gate] XX at ZZZ.


Second narrative: On DATE approximately XA50 local; at Gate XX at ZZZ; while at the gate with the tug driver having control of the aircraft; another airline; attempted to enter their gate ended up running their right wing into our left wing. Our aircraft was not moving during the impact. We were at the gate with the jet bridge not connected. Ramp control had given our clearance to push back to spot after giving way to aircraft entering the gate at XY (gate to our left). We relayed this information to the tug driver and they acknowledged us. Then about ten seconds later the tug driver had asked the Captain to set the brake. We saw rampers running towards our aircraft and that is when the Captain had seen that the other aircraft had ran their right wing into the back of our left wing while entering their gate. After determining that there was no emergency that required emergency services; we had a jet bridge driver come back down so we could deplane the aircraft. We contacted Company and Maintenance came out to the aircraft. No passengers or crew members were injured. Our aircraft was stationary at the time and we were struck by another aircraft. In addition; the aircraft was under the control of contract rampers when the incident occurred. As a result; the incident was not the result of any action or inaction on the contractors part and any recommendations for preventing future incidents of this nature would involve third parties.


Synopsis: Air carrier flight crew reported an aircraft parking at the adjacent gate made contact with their wingtip while sitting at the gate waiting for push back.
