Overview
This is a list of members of the Union Cabinet of the Government of India, 2004 to May 2009.

All ministers are based in offices of their respective Union Ministries in New Delhi. All Cabinet members are mandated by the constitution to be members of either house of the Parliament of India. In a departure from the norm the current Prime Minister, Manmohan Singh, is a member of the Upper House, the Rajya Sabha, and has remained so for the duration of his entire term (2004–2009).

There are three categories of ministers, in descending order of rank:
 * Union Cabinet Minister - Senior minister in-charge of a ministry. A Cabinet minister may also hold additional charges of other Ministries, where no other Cabinet minister is appointed
 * Minister of State (Independent Charge)- with no overseeing Union Cabinet Minister for that portfolio
 * Minister of State (MoS) - junior minister with an overseeing Cabinet Minister, usually tasked with a specific responsibility in that ministry. For instance, an MoS in the Finance Ministry may only handle Taxation
