Iodidimonas is a genus of bacteria that oxidizes elemental iodide (I⁻) to molecular iodine (I₂). It was isolated from iodide-rich brine associated with methane gas in Kujukuri, Japan. ^{[1] [3]}

Geiger et alii (2023) suggest that Iodidimonas may be the closest living relative of mitochondria. ^[4] If true, this lineage and protomitochondria emerged from a common ancestor before the symbiogenetic event that gave rise to the eukaryotes. ^[5]
