Oberon je jeden ze čtyř největších Uranových měsíců (společně s měsíci Ariel, Umbriel a Titania).
Od planety je vzdálen 583 520 kilometrů. Jeho poloměr je 761,4 kilometrů a hmotnost cca 3,014×1021 kg, oběžná doba je 13,4632 dne.
Byl objeven Williamem Herschelem už 11. ledna 1787. Podrobnější průzkum provedla a snímky měsíce pořídila sonda Voyager 2 při svém průletu v lednu 1986.
Podobně jako ostatní měsíce Uranu nese Oberon své jméno podle jedné z postav díla Williama Shakespeara.

Voyager 2 picture of Oberon.jpg
Original Caption Released with Image: This Voyager 2 picture of Oberon is the best the spacecraft acquired of Uranus' outermost moon. The picture was taken shortly after 3:30 a.m. PST on Jan. 24, 1986, from a distance of 660,000 kilometers (410,000 miles). The color was reconstructed from images taken through the narrow-angle camera's violet, clear and green filters. The picture shows features as small as 12 km (7 mi) on the moon's surface. Clearly visible are several large impact craters in Oberon's icy surface surrounded by bright rays similar to those seen on Jupiter's moon Callisto. Quite prominent near the center of Oberon's disk is a large crater with a bright central peak and a floor partially covered with very dark material. This may be icy, carbon-rich material erupted onto the crater floor sometime after the crater formed. Another striking topographic feature is a large mountain, about 6 km (4 mi) high, peeking out on the lower left limb. The Voyager project is managed for NASA by the Jet Propulsion Laboratory.
