The following is a list of the longest-serving members of the Parliament of India with overall tenures in office totaling at least 30 years. The present bicameral Parliament is a continuation of the unicameral Provisional Parliament established on 26 January 1950. Parliamentarians with service in the Provisional Parliament of India (26 January 1950âÂÂ5 March 1952), the Rajya Sabha and the Lok Sabha (from 1952) are included.
Tenures begin from the date the respective member initially took their oath or affirmation of office, and end with either the dissolution date of that Lok Sabha or with the date the member vacated their seat. If two members have tenures of identical length, they are ranked by seniority in the order they took their seats in a given chamber, where applicable. Unless otherwise referenced, dates are from the official websites and records of the respective parliamentary debates.
