4183 Cuno is an Apollo, Mars- and Venus-crosser asteroid. It was discovered in 1959 by Cuno Hoffmeister, from whom the asteroid takes its name.

Cuno is about 4-9 km in diameter and is an S-type asteroid, meaning that it is highly reflective and composed of nickel-iron mixed with iron- and magnesium-silicates.

In December 2000, Cuno was analysed by radar to determine its shape. The resultant images are lacking in detail, but indicate a rough sphere with some kind of concave depression 1-2 km in diameter.

4183 Cuno approaches the Earth to within 40 Gm six times in the 21st century. In 2012 it makes its closest pass, at 18 Gm, until 2093.
