R-value can refer to:
- Properties of materials:
- R-value (insulation), the efficiency of insulation of a house
- R-value (soils), stability of soils and aggregates for pavement construction
- value (computer science)#lrvalue, in computer science, a value considered independently of the "place" it is located
- 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
- In the physical sciences, the gas constant is often denoted by the symbol R
- In ophthalmic optics, r-value refers to the distance between the segment optical center and the segment top
- Lankford coefficient
