Chimalpopoca (Classical Nahuatl: Chīmalpopōca [t͡ʃiːmaɬpoˈpoːka] for "smoking shield," modern Nahuatl pronunciation ) (1397–1427) was the third king of Tenochtitlan (1417–1427).

Chimalpopoca was born to the King Huitzilihuitl and Queen Ayauhcihuatl.

On the day of Chimalpopoca's coronation in 1417 (some sources say 1416 or 1418), his brother Tlacaelel I was named high priest. From this point on the ecclesiastical and governmental offices among the Aztecs were separate.

When he assumed the throne at age 20, Tenochtitlan was a tributary of the Tepanec city of Azcapotzalco, which was ruled by his grandfather Tezozomoc. This alliance, and the Mexicas' position within it, was strengthened by Tenochtitlan's loyalty during Tezozomoc's 1418 war with Ixtlilxochitl I of Texcoco. The conquered city was granted to Tenochtitlan as a tributary.

Nezahualcoyotl, displaced prince of Texcoco, was living in the mountains. Chimalpopoca interceded with Tezozomoc on his behalf, and Tezozomoc agreed to allow Netzahualcoyotl to live in Tenochtitlan under his protection.

In 1426 Tezozómoc assisted Chimalpopoca in the construction of a new aqueduct. This aqueduct was of wood, and ran from the elevated place of Chapultepec to Tenochtitlan.
