The voting results are for the 13 December 2009 Chamber of Deputies election.

Senatorial constituencies

There are 19 senatorial constituencies (circunscripción senatorial). Each region constitutes a senatorial constituency, except regions V, RM, VII, VIII and IX, which are each divided into two senatorial constituencies. Each senatorial constituency elects two senators. Senatorial constituencies which are not full regions are made up of several electoral districts within a region.

In 2009 the Constitution was modified so that each region constitutes at least one senatorial constituency. The law determining senatorial constituencies has not been revised to reflect this change, so the list continues to be as follows:
