The LV Legislature of the Congress of the Union of Mexico (55th Congress) met from 1 September 1991 to 31 August 1994.

32 senators and all of the deputies had been elected in the 1991 legislative elections. The deputies served three years and the senators six, continuing into the 56th Congress.

The PRI regained near-total control of the legislature, with nearly two-thirds of the deputies and all but three senators.
