Soft soap can refer to one of the following:
- a general purpose soap that is liquid or easily soluble, as opposed to a hard soap which will only dissolve sparingly.
- a hygiene product made exclusively from natural oils. In this case "soft" prefix is a reference to it being "softer on nature" than regular, synthetic soaps.
- a term for "flattery" and "blarney", especially when applied to ingratiating praise intended to persuade, cajole or wheedle a favor.
- Softsoap (without a space) is the trade name of a liquid soap product.
