Plutinos
Found in the inner parts of the Kuiper Belt, plutinos are Kuiper Belt objects (KBOs) that have orbital periods very similar to that of Pluto.
Plutino
In astronomy, a plutino is a trans-Neptunian object that has a 2:3 orbital resonance with Neptune. They are named after Pluto, which also has this same orbital resonance1.

objects which, like , have semi-major axes of AU and are is a 3:2 orbital resonance with . Some are also in -crossing orbits, like . Of the 32 observed objects (plus itself), Jewitt and Luu have identified 13 plutinos.

plutino: One of the icy Kuiper belt objects that, like Pluto, are caught in a 3:2 orbital resonance with Neptune.
polar axis: The axis around which a celestial body rotates.
Plutinos and cubewanos are two classes of trans-neptunian objects. Plutinos have a similar orbit to Pluto because a gravitational resonance from Neptune works to stabilize the objects.

Many Plutinos share properties of the high eccentricities and significant inclinations with Pluto. It is therefore natural to associate the presence of so many Plutinos with their interesting orbital properties.

Hence, it has been classified as "Plutino" -- an EKO in an orbit that goes around the Sun twice for every three times that Neptune orbits around the Sun.

Originally considered a planet, it has many physical properties in common with the objects of the Kuiper belt, and has been known since the early 1990s to share its orbit with a number of similarly-sized KBOs, now called Plutinos.
Pluto is sometimes classified as a Kuiper belt object in addition to being a planet, and a class of Kuiper belt objects with Pluto-like orbits are called Plutinos.
By 1996, over 30 such objects were observed, and as of November 2007, over 1000 (also see here). Many are locked in a 2:3 resonance the way Pluto is (those have been dubbed "Plutinos") and others display different resonances, ...
CUBEWANO
A Cubewano is a main Kuiper belt objects, ones that are not influenced by the resonances of the outer planets. Cubewanos are farther from the Sun than about 41 AU. Compare with Plutino.

Pluto lies in the resonant belt, having a 3:2 resonance with Neptune (it orbits twice round the Sun for every three Neptunian orbits). Kuiper belt objects whose orbits share this resonance are called plutinos.
