The Tlapanec /ˈtlæpənɛk/, or Meꞌphaa, are an indigenous people of Mexico native to the state of Guerrero.

Today, Tlapanecs live primarily in the state of Guerrero and number more than 98,000.

In pre-Columbian times they lived in the isolated mountain area along the Costa Chica region of Guerrero, just southeast of present-day Acapulco.

Their territory was called Yopitzinco by the Aztecs who also referred to the Tlapanecs as Yopi[pronunciation?].

The Tlapanecs explain natural phenomena through myth, like the myth of the creation of the sun (Akha'), the moon (Gon') and the fire god (Akuun mbatsuun'), who all were born on the bank of the river and who were raised by Akuun ñee, goddess of the temazcal sweatbath and patron of the hot/cold duality.
