Rajya Sabha elections were held in 2018 to elect the 65 retiring members of the Rajya Sabha, Indian Parliament's upper chamber.

Being even-numbered, 2018 was a year in which about 30% of the State Legislature-elected 233-seat component of the body is elected.

Not as part of a six-yearly cycle, a by-election was held to elect 1 member from Kerala in March, which proved to be a re-election but as an independent member, of M. P. Veerendra Kumar, the only by-election of the year.

Sikkim had an election for 1 Rajya Sabha seat on 16 January 2018 to replace member retiring on 23 February 2018.

In addition to scheduled elections, unforeseen vacancies, caused by members' resignation, death or disqualification, may also be filled via By-elections.
