Regional distribution of salinity refers to the distribution of salinity in various individual oceans of the world. Because of the absence of uniformity in the controls of salinity, there art variations in the distribution of salinity in different parts of the oceans.

There are two approaches to discuss the distribution of salinity on a regional scale. The first approach describes the salinity distribution in individual oceans separately.

While the second approach, adopted by Jenkins, discusses the salinity by classifying all the oceans and seas of the world into three categories in respect of salinity, i.e. above normal, normal and below normal.

Here the first method has been followed, and a brief discussion of the individual oceans has been presented.
