Narrative:

We landed safely and without incident in ZZZ a few minutes early. We cleared the runway onto the taxiway and started toward our gate. I turned the corner there at the intersection of [the runways] and proceeded the gate. I slowed the taxi until I found my ground crew and then proceeded as I had all three in place. I was on the taxi centerline and was being marshalled into the gate. I passed the first wing walker on the left and then shifted my focus to the second wing walker on the right and the marshal on the lead in line. The two wing walkers were giving their clearance sign and the marshal was waving me into the gate. Before I made my turn I felt the impact and stopped immediately. I set the parking brake and leaned out my window to see what happened. I could see that I had clipped the right winglet [of another aircraft] with my left winglet and started coordinating with the ground crew out my window. I made a passenger announcement after a few minutes and informed the passengers of possible contact with the parked aircraft next to us and to remain seated until we could get everyone off the plane. The ground crew pulled up a ramp a few minutes later and the passengers were de-planned. There were no injuries to any passengers; crew or ground personnel. The police and fire departments came and inspected the damage. I was able to spend a considerable amount of time inspecting the damage and positioning of both aircraft.I believe there were multiple causes that contributed to the event; none of which I really had any control over. I was right on the centerline of what is already a very narrow taxi way following the directions of my ground personnel. The [other aircraft] was several feet out of position in gate and its wingtip a foot or more past the safety margin for [the] gate. The wing walker standing right by that wing may have been inattentive and allowed the taxi to continue. At no time until there was impact was there ever a stop indication from the ground personnel.I am not sure what could be done different operationally other than not to park in that gate. The taxi way is very narrow and you essentially close [the] runway when you make the turn onto the taxiway. There is always pressure to get the plane into the gate as quickly as possible to avoid disrupting take-offs. Better ground personnel training would also have helped significantly.
