MS Regula is a passenger and vehicle ferry built in Germany by Meyer Werft and launched in 1971.

Regula was the second of three identical sister vessels, and had an initial capacity of 800 passengers and 75 cars.

[1] After 26 years of service in Scandinavia, in 1997 Regula was sold to Saaremaa Shipping Company of Estonia to serve its routes between the Estonian mainland and the islands of Saaremaa and Hiiumaa in the Baltic Sea.

[2] Both Regula and operations on the island routes were taken over by TS Laevad in 2016.
