SS Royal Daffodil was a Mersey ferry, built in 1906 and scrapped in 1938.

[2] She was put into service as one of the Mersey ferries operating between Liverpool and Wallasey.

[5][6] Both the Iris and the Daffodil were towed across the English Channel by HMS Vindictive for the operation on 23 April 1918.

[7] As the attack unfolded, Daffodil was hit in the engine room by two shells, but was able to maintain her position holding Vindictive against the wall of the Mole.

The NMSPC was taken over by the General Steam Navigation Co. Ltd. in 1936 and in 1938 Royal Daffodil was sold for scrapping in Belgium.
