**Percentage solution** may refer to:

- [Mass fraction](/source/Mass_fraction_(chemistry)) (or "% w/w" or "wt.%"), for percent mass
- [Volume fraction](/source/Volume_fraction) (or "% v/v" or "vol.%"), volume concentration, for percent volume
- "Mass/volume percentage" (or "% m/v") in biology, for mass per unit volume; incorrectly used to denote [mass concentration (chemistry)](/source/Mass_concentration_(chemistry)). See [usage in biology](/source/Mass_concentration_(chemistry)#Usage_in_biology)
