Germana adalah senyawa kimia dengan rumus GeH4, dan merupakan analog germanium dari metana. GeH4 adalah senyawa germanium hidrida yang paling sederhana dan salah satu senyawa germanium yang paling berguna. Seperti silana dan metana, germana memiliki bentuk molekul tetrahedral. Senyawa ini akan terbakar di udara dan menghasilkan GeO2 dan air. Germana adalah salah satu senyawa hidrida golongan 14.
Keterjadian
Germana telah terdeteksi di atmosfer Jupiter.[3]
