隱孢子蟲屬（學名：Cryptosporidium）是頂複門的一個屬，本屬部分物種可感染包括人類在內的許多脊椎動物，造成隱孢子蟲病，症狀包括腹瀉與咳嗽等^[1]。

感染

隱孢子蟲與瘧原蟲和弓形蟲皆為頂複門的寄生蟲，有別於後兩者，隱孢子蟲的生活史中不需中間宿主^[2]。隱孢子蟲病多為短期、急性的疾病，感染後隱孢子蟲可生存在人類的腸道長達五週，造成腹瀉等症狀^[1]。在體外隱孢子蟲以卵囊的形式存在，對環境的抗性很高，進入人體後即可感染小腸上皮組織。造成人類隱孢子蟲病的物種大多是小隱孢子蟲與人隱胞子蟲（英語：Cryptosporidium hominis）兩種，不過犬隱孢子蟲（C. canis）、貓隱孢子蟲（C. felis）、火雞隱胞子蟲（C. meleagridis）與鼠隱孢子蟲（英語：Cryptosporidium muris）也可能感染人類^[2]。免疫缺陷者被感染的症狀一般較嚴重，但免疫正常者也可能被感染^[2]。

基因組

2004年，小隱孢子蟲的基因組被完整定序，發現其粒線體中不含有DNA^[3]。
