'''2M1207b''' adalah [[Planet#Benda bermassa planet|objek bermassa planet]] yang mengorbit sebuah katai coklat [[2M1207]], di konstelasi [[Centaurus]], sekitar 170 tahun cahaya dari Bumi. Objek ini adalah salah satu kandidat exoplanet pertama yang dapat diamati secara langsung (dengan pencitraan [[inframerah]]). Planet ini ditemukan pada bulan April 2004 oleh [[Very Large Telescope]] (VLT) di [[Observatorium Paranal]] di Chili oleh tim dari [[European Southern Observatory]] yang dipimpin oleh [[Gaël Chauvin]]. Planet ini diduga memiliki massa antara 3 sampai 10 kali massa Jupiter dan mungkin mengorbit 2M1207 pada jarak yang setara dengan Pluto ke Matahari.
