Aspidoscelis sackii, known commonly as Sack's spotted whiptail, is a species of lizard in the family Teiidae.

The specific name, sackii, is in honor of German explorer Baron Sebastian Albert von Sack.

[2] Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Aspidoscelis.

A. sackii is found in the Mexican states of Chiapas, Guerrero, Mexico City, Michoacán, Morelos, Oaxaca, Puebla, and Tamaulipas.

[2] The preferred natural habitats of A. sackii are forest, shrubland, and desert.
