A very far second would be the solid state of matter. Osmium and Iridium are transition metals which have the hightest atomic densities; Os has 22.5 g/cm^3, Ir has 22.4 g/cm3 at 20°C and 1013 mbar.
Neutron Star material is by far the densist material possible (it is made up of just neutrons and protons). Density is about 10^15 g/cm^3. (One hair would weigh a ton).
A typical neutron star has a mass between 1.4 and 5 times that of the Sun. It cannot be more massive than this or gravity will overwhelm it and it will become a black hole! The radius of a neutron star may be between 10 and 20 kilometers.

The four states of matter are plasma. gas, liquid and solid.
In comparing densities though, which is one way of differentiating one substance from another, we usually refer only to the three common states- gas, liquid and solid.
In this case, solids are the densest and the gases are least dense. For comparison, the commonly accepted densest solid - the metal iridium, has a value of about 22650 kg/m³. On the other hand, gases are about 1 or less than 1 kg/m³. Liquids have values in between.

Solids have the highest density, then comes liquids, and finally gases.

solids are the most dense, then liquid, then gas (least dense).
