This review shows the great impact of charge ordering upon the magnetic and transport properties of mixed valent Co4+/Co3+ and Co3+/Co2+ cobalt oxides. The relationships between charge ordering and physical properties are described for three structural families the ordered oxygen deficient perovskites and the Ruddlesden and Popper (RP) derivative La1.5Sr0.5CoO4, the layered NaxCoO2 series and the "114" CaBaCo4O7 oxide.
