隐球菌病（英语：Cryptococcosis、Cryptococcal disease）是一种可能致命的真菌疾病，由一或二种真菌造成：新型隐球菌（Cryptococcus neoformans）与Cryptococcus gattii，两者原本都被认为是Cryptococcus neoformans的变种，但现在被分成两个不同的物种。

隐球菌病通常是藉吸入有感染力的繁殖体而感染，但繁殖体具体的形式还不确定，目前较被接受的说法是经有性或无性过程产生的担孢子。

Cryptococcosis, also known as cryptococcal disease, is a potentially fatal fungal disease. It is caused by one of two species; Cryptococcus neoformans and Cryptococcus gattii. These were all previously thought to be subspecies of C. neoformans but have now been identified as distinct species.
