The official seal of the City of Marikina bears the inscription Lungsod ng Marikina, Pilipinas, 1630 corresponding to the date of founding of the municipality, and 1996 as the year of approval of the city charter. The two mountains represent the Cordillera and Sierra Madre that form the Marikina Valley, transgressed by the Marikina River.

The rising sun pinpoints the eastern location of the city, with each ray representing the city's fourteen barangays. The gear symbolizes its industry and the shoelast represents the traditional manufacture of the city. The Roman torch focuses on the lofty and noble ideals for human development, for a better quality of life, and symbolic of its hispanic culture and tradition.

The bamboo underscores a mixture of the peoples' natural humility and strength of character and also puts emphasis on the transition from its agricultural past to industrial present, while the leaves and branches symbolize order and serenity. The bamboo and the wheel represent protection of the environment to remain in harmony with progress.

The Marikina City Symbol focuses on the character of its people represented by a man wearing a "salakot" (headgear) and "camisa de chino" ( chinese shirt) framed by an arch.

The salakot traces the man's native origin, the camisa de chino his oriental character and the arched framed his hispanic past. The arched frame also represents the community and the limits of one's individuality.

The faceless head personifies the individual who is one with his community, one who lives by the norms of good conduct ( mabuting ugali), in harmony with his neighbor and one who gives honor to his community as he does to himself.

DISCIPLINE, GOOD TASTE AND EXCELLENCE are traits represented by the shirt buttons as one's commitment to pursue with zeal and ardor.
