The Volapük ü, Ꞟ in upper case and ꞟ in lower case, was an additional letter of the Latin alphabet that was used in the writing of Volapük in the 19th century. It is now transcribed 'Ü' and 'ü' in Volapük.

Volapük Ä, ö, and ü in a Volapük grammar sheet by Schleyer in 1884.

Volapük ä, ö, and ü used by Julius Lott in 1888.

This letter was proposed by Johann Martin Schleyer, with the letters ae ‹Ꞛ ꞛ› and oe ‹Ꞝ ꞝ› for the writing of the Volapük and was used briefly.

This letter, as well as the letters Ꞛ and Ꞝ were replaced in Volapük writing by the Latin letters with umlaut ‹Ä ä, Ö ö, Ü ü› at the Munich Congress of 1887.
