A cup holder assembly includes a body that defines a cup-receiving cavity and an aperture that extends through a side wall of the body, a first bracing feature and a second bracing feature, each of which is coupled to the body and positioned outside of the cup-receiving cavity, and a retention finger. The retention finger includes a first portion that extends into the cup-receiving cavity through the aperture, a first engagement feature coupled to the first portion and pivotably engaged with the first bracing feature, and a second engagement feature coupled to the first portion and engaged with the second bracing feature. The retention finger is operable to move via pivotal movement of the first engagement feature relative to the first bracing feature.
