Sodium polonide is a chemical compound with the formula Na2Po. It is a polonide, a set of very chemically stable compounds of polonium. Due to the difference in electronegativity (ΔEN) between sodium and polonium (≈ 1.1 under the Pauling system) and the slight non-metallic character of polonium, it is intermediate between intermetallic phases and ionic compounds.

- H2Po + 2 Na → Na2Po + H2
This method of synthesis is hampered by the chemical instability of hydrogen polonide.
