相對滲透率（relative permeability）是多相流體在岩石或土壤等多孔介質中流動時的關鍵參數，用于描述某一相流體在存在其他流體時的有效滲透率與岩石絕對滲透率的比值。其數學表達式為： $$ K{ralpha} = frac{K{alpha}}{K} $$ 其中，$K{ralpha}$表示α相流體的相對滲透率，$K{alpha}$為α相的有效滲透率，$K$為岩石的絕對滲透率。

在石油地質和工程中，相對滲透率（relative permeability）指多孔介質（如岩石）中多相流體（油、水、氣）共存時，某一相流體的有效滲透率與絕對滲透率的比值。
| 領域 | 定義 | 典型值 | 應用實例 |
|---|---|---|---|
| 磁學 | 材料磁導率與真空磁導率的比值 | 鐵氧體：$mu_r approx 10$ | 變壓器、電磁鐵設計 |
