Roughness may refer to:

• Surface roughness, the roughness of a surface
• International Roughness Index, the roughness of a road
• Hydraulic roughness, the roughness of land and waterway features
• Roughness in psychoacoustics refers to the level of dissonance.
• The 'roughness' of a line or surface, measured numerically by the Hausdorff dimension
• A typical parameter that has been used to quantify the quality of a surface topography is the surface roughness, which is represented by the arithmetic mean value, Ra, the root mean-square-average, Rq, and the maximum roughness height, Rt.
