A Group 8 element is the series of elements in group 8 (IUPAC style) in the periodic table, which consists of the transition metals Iron (Fe), Ruthenium (Ru), Osmium (Os) and Hassium (Hs).

All of these elements are classed in Group 8 because their valence shell holds four electrons. Hassium can only be produced in the laboratory and has not been found in nature.
