HD 93083 b is an extrasolar planet orbiting the star HD 93083. It is probably much less massive than Jupiter, although only the minimum mass is known. The planet's mean distance from the star is about half that of Earth, and the orbit is slightly eccentric.

There could be an Earth sized planet in its Trojan field.
