Huehue Acamapichtli (Ācamāpichtli [aːkamaːˈpit͡ʃt͡ɬi] = "Handful of reeds," modern Nahuatl pronunciation ) was a king (Spanish language: rey; Nahuatl: tlatoani) of Culhuacán in Mexico.
He was a son — and successor — of King Coxcoxtli and his wife.
His sister was Atotoztli I of Culhuacán — mother of tlatoani of Tenochtitlan, named also Acamapichtli.
Diego Durán, Fernando Alvarado Tezozómoc and Fernando de Alva Cortés Ixtlilxochitl mentioned that Huehue Acamapichtli occupied the throne of Culhuacan in 1324.
