Johannes Baptista von Albertini (17 February 1769 – 6 December 1831) was a German botanist, mycologist and clergyman of the Moravian Church.

In 1814 he was elected bishop, and in 1824 was chairman of the Unitätsältestenkonferenz, the denomination's executive board, in Berthelsdorf.

He was a gifted speaker and a highly influential minister, and in 1805 a compilation of his sermons was published as 30 Predigten für Freunde und Mitglieder der Brüdergemeine (Thirty Sermons for Friends and Members of the Moravian Brethren's Church).

In the field of mycology he was co-author with Lewis David de Schweinitz (1780–1834) of a work on Upper Lusatian fungi titled Conspectus Fungorum in Lusatiae superioris agro Niskiensi crescentium e methodo Persooniana.

The plant genus Albertinia within the family Asteraceae was named in his honor in 1821.
