"We won't forget you," tweeted acting Spanish PM Mariano Rajoy.
A further 1,800 people were injured in the devastating attacks in which four trains were targeted by an al-Qaeda-inspired cell.
Rajoy stressed that the fight against terrorism remains "a priority" for Spain and "all the countries that have been hit, and harshly, over recent years".
"Spain will continue to defend, as it has always done, the lives, rights and freedom of its citizens, both within Spain and abroad," added Rajoy.
After meeting under the plaque to honour the victims at Madrid's central Puerta del Sol at 9am, the ceremony moved to Atocha train station, scene of three of the bombings on the morning on March 11th 2004.
