**Brom** silih tunggil datu kimia dengan simbol **Br** miwah wilangan atom 35. Punika halogén pinih ingan katiga, miwah marupa éncéh soklat-bang maandus ring suhu kamar sané aluh nguap ngawentuk uap mawarna pateh. Cecirén nyané punika sauntara klorin miwah yodium. Kaisolasi sacara ngaraga olih kalih juru kimia, Carl Jacob Löwig (warsa 1825) miwah Antoine Jérôme Balard (warsa 1826), aran nyané maasal saking Basa Yunani Kuna βρῶμος ("ambu tan becik"), mawit saking ambu nyané sané keras miwah tan miik.
