The Senate (Spanish: Cámara de Senadores or Senado) is the upper house of Mexico's bicameral Congress.

After a series of reforms during the 1990s, it is now made up of 128 senators:

• Three for each of the 31 states
• Three for the Federal District
• Thirty-two national senators-at-large, divided among the parties in proportion to their share of the national vote.

In each state (and the Federal District), the party that wins the senatorial race returns two of that state's three senators; the party that secures the second-highest vote is awarded the third seat.

Party strengths in the Senate for the 2000-06 period stand as follows (figures as of January 2004):

• Institutional Revolutionary Party (PRI) = 60
• National Action Party (PAN) = 46
• Party of the Democratic Revolution (PRD) = 16
• Green Ecological Party of Mexico (PVEM) = 5
• Convergencia = 1
