Annales Botanici Fennici is a bimonthly peer-reviewed scientific journal covering the systematics, taxonomy, and nomenclature of fungi and plants.

[1][2] The journal also accepts articles on population biology, physiology, molecular biology, climate change, ecology and invasive species, phytogeography, and paleoecology.

[3] It replaced two previous series which had been in circulation from 1923 to 1963 called Annales Botanici Societatis Zoologicae Fennicae Vanamo and Archivum Societatis Zoologicae Fennicae Vanamo.

The purpose of it was to print longer, more comprehensive monographs at least 64 pages long which did not fit into the short quarterly format of the Annales.

[3] Beginning in 2022, the journal moved to an online-only format starting with its 59th volume.
