The Mexican Liberal Party was a Mexican political party that had legal registration between 2002 and 2003 with the same name as the old Mexican Liberal Party founded by Ricardo Flores Magón in 1906.
The PLM intended to be an heir of the historic party as well as of the liberal principles by those that had fought in the Reform War, which principles the PLM asserted that the advanced modern political party of Mexico had abandoned.
The PLM participated in the 2003 elections but did not obtain the minimum number of votes required by law, for which it lost its registration and disappeared.
