The 1993–94 National Division 5 South was the seventh full season of rugby union within the fifth tier of the English league system, currently the regional divisions Regional 1 South East and Regional 1 South West, and the first using the name National Division 5 South, with its counterpart being National Division 5 North. The introduction of a new National Division 4 meant that the old National Division 4 North and South was merged and two new regional leagues introduced at tier 5.

New promoted Reading finished the season as champions and gained promotion to the 1994–95 National Division 4, while Maidstone and Southend finished as the bottom two sides, both being relegated down to London Division 1.
