R-value can refer to:
- Properties of materials:
- R-value (insulation), the efficiency of insulation
- R-value (soils), stability of soils and aggregates for pavement construction
- r-value, in computer science, a value that does not have an address in a computer language
- R-factor (crystallography), a measure of the agreement between the crystallographic model and the diffraction data
- In statistics, r (or r value) refers to the Pearson product-moment correlation coefficient, often called simply correlation coefficient
