We present the results of ISOCAM observations at 6.75 and 14.3 µm, and near-IR spectra of a selected sample of candidate young brown dwarfs and very low-mass young stellar objects in the Chamaeleon dark cloud complex. We confirm the object Cha Hα 1 (ISO-Cha I 95) as a bona fide young brown dwarf and identify four new young objects in Cha I (ISO-Cha I 138, 143, 235 and 250) with spectral types ≥ M6 and masses close to the hydrogen burning limit. Another new candidate young sub-stellar system has been detected in the core of the Cha II dark cloud (ISO-Cha II 13). All these sources show significant mid-IR excesses probably due to the presence of circumstellar disks.
