The Arjuna asteroids are a class of near-Earth asteroids whose orbits are very Earth-like in character, having low inclination, orbital periods close to one Earth year, and low eccentricity. Arjunas are very uncommon, but of significance owing to the extremely low delta V required to reach them from Earth.

The Arjuna definition is somewhat fuzzy and covers the definition of the three well-established families Apollo, Amor and Aten.

Note that there is no asteroid named "Arjuna" (whereas there are namesake asteroids 1862 Apollo, 1221 Amor and 2062 Aten).
