Embodiments disclosed herein relate to carabiners, carabiner retrieval devices and systems, and methods of retrieving a carabiner. In an embodiment, a carabiner retrieval device includes a neck, a retention device, and a retrieval cord retention structure. The neck has a length and includes a first end spaced from a second end along the length. The retention device extends from the first end of the neck at an obtuse angle relative to the length of the neck, and is configured to be attached to a gate of a carabiner. The retrieval cord retention structure extends from the second end of the neck, and is configured to retain a retrieval cord. When the retrieval cord is coupled to the retrieval cord retention structure and the retrieval cord retention device is attached to the gate of the carabiner, the gate opens responsive to the retrieval cord being pulled in a predetermined direction.
