This is a list of exoplanets discovered before 2000.^[1]

For exoplanets detected only by radial velocity, the mass value is actually a lower limit. (See Minimum mass for more information.)

While the existence of a substellar companion to Gamma Cephei was suspected since 1988,^[2] the planet Gamma Cephei Ab was not confirmed until 2003,^[3] and that is listed as its discovery year in exoplanet databases. Thus, this planet is in the List of exoplanets discovered between 2000–2009.

HD 114762 b was once considered as the first discovered exoplanet. Found in 1989 by a team led by David Latham, it is now known to be a red dwarf star.^[5]
