  Charge ordering is one of the most intriguing and extensively studied
phenomena in correlated electronic materials because of its strong impact on
electron transport properties including superconductivity. Despite its
ubiquitousness in correlated systems, the occurrence of charge ordering in
iron-based superconductors is still unresolved. Here we use scanning tunneling
microscopy to reveal a long-range charge-stripe order and a highly anisotropic
dispersion of electronic states in the ground state of stoichiometric FeTe, the
parent compound of the Fe(Te, Se, S) superconductor family. The formation of
charge order in a strongly correlated electron system with integer nominal
valence (here Fe$^{2+}$) is unexpected and suggests that the iron-based
superconductors may exhibit more complex charge dynamics than originally
expected. We show that the present observations can be attributed to the
surpassing of the role of local Coulomb interaction by the poorly screened
longer-range Coulomb interactions, facilitated by large Hund's rule coupling.
