#### Abstract

Based on first principles calculations, the electronic structure of CuTeO\$_4\$ is discussed in the context of superconducting cuprates. Despite some significant crystallographic differences, we find that CuTeO\$_4\$ is similar to these cuprates, exhibiting a quasi two dimensional electronic structure that involves hybridized Cu-\$d\$ and O-\$p\$ states in the vicinity of the Fermi level, along with an antiferromagnetic insulating ground state. Hole doping this material by substituting Te\$^{6+}\$ with Sb\$^{5+}\$ would be of significant interest.
