The 2007 Madrilenian regional election was held on Sunday, 27 May 2007, to elect the 8th Assembly of the Community of Madrid. All 120 seats in the Assembly were up for election. The election was held simultaneously with regional elections in twelve other autonomous communities and local elections all throughout Spain. Because regional elections in the Community of Madrid were mandated for the fourth Sunday of May every four years, the October 2003 snap election did not alter the term of the four-year legislature starting in May 2003.

The Assembly of Madrid or Madrid Assembly is the unicameral autonomous legislature of the Autonomous Community of Madrid since the approval of the Madrid Charter of Autonomy in 1983.
