Tlacopan, also calledTacuba, (Classical Nahuatl:Tlacōpan,[t͡ɬaˈkóːpan̥]) was aTepanec /Mexicaaltepetl on the western shore ofLake Texcoco. The site is today the neighborhood ofTacuba, inMexico City.

The name comes fromClassical Nahuatltlacōtl, "stem" or "rod" and-pan, "place in or on" and roughly translates to "place on the rods"),^[1]

Tlacopan was aTepanec subordinate city-state to nearby altepetl,Azcapotzalco.

In 1428, after its successful conquest of Azcapotzalco, Tlacopan allied with the neighbouring city-states ofTenochtitlan andTexcoco, thus becoming a member of theAztec Triple Alliance and resulting in the subsequent birth of theAztec Empire.^{[2]: xxxviii}

Aculnahuacatl Tzaqualcatl, the son of the Tepanec ruler,Tezozomoc, was installed astlatoani of Tlacopan until his death in c.1430. Throughout its existence, Tlacopan was to remain a minor polity within the Triple Alliance. It received only a fifth oftribute earned from joint campaigns with its more powerful allies.

In 1521, the Aztec Empire collapsed as a result of the Spanish conquest of Mexico, led byHernán Cortés and his nativeTlaxcallan allies. Over the next few centuries, Tlacopan has been assimilated into the sprawling mega-metropolis ofMexico City. The archæological site of Tlacopan is located inTacuba, within the present-day municipality ofMiguel Hidalgo.
