68 Draconis is the Flamsteed designation for a star in the northern constellation of Draco. It has an apparent visual magnitude of 5.69, so, according to the Bortle scale, it is faintly visible to the naked eye from suburban skies at night. Measurements made with the Hipparcos spacecraft show an annual parallax shift of 0.02068″, which is equivalent to a distance of around 158 ly (48 pc) from the Sun.

The stellar classification of 68 Draconis is F5 V, indicating that it is a main sequence star that is fusing hydrogen into helium at its core to generate energy. The star appears to be over-luminous for a member of its class, being 0.73 magnitudes brighter than expected. This may indicate that this is a binary system with an unresolved secondary component. It is less than half as old as the Sun, with an estimated age of 1.7 billion years. The effective temperature of the stellar atmosphere is 6,137 K, giving it the yellow-white hue of an F-type star.
