A stemware holder maintains a piece of stemware in an upright position even during turbulent conditions. An embodiment has a base extending downward from a cap. The cap has a lower portion with a flat surface and an upper portion with two prongs that define a slot. A wall extends around part of the perimeters of the upper and lower portions and has a front opening. The upper and lower portions, partial perimeter wall, and front opening define a groove. The groove narrows slightly from the front to the rear. The stemware holder base is insertable into the recess of a standard cup holder. The base of a piece of stemware can be slid into the groove through the front opening with the stem extending through the slot. The prongs and groove collectively assist in maintaining the stemware upright. Another embodiment employs a similar cap that is fixable directly to a surface without insertion into a cup holder recess.
