We discuss the prospects for brown dwarf detections in the field and in star-forming regions using data from the SIRTF Legacy Science Programs. We concentrate in particular on the SIRTF Wide-area InfraRed Extragalactic survey (SWIRE) and “From Cores to Disks” program (c2d). The SWIRE program will map up to 70 square degrees of high galactic latitude sky, providing wavelength coverage from 3.6 to 160 μm. SWIRE's estimated 5σ sensitivity of 10 microJy at 4.5 μm and its relatively large areal coverage will make it uniquely sensitive to the population of extremely cool (T ≤ 600 K) field brown dwarfs thus far undetected in other surveys. The “c2d” program will map up to 20 square degrees in nearby (d ≤ 300 pc) star-forming molecular clouds over the wavelength range 3.6 – 70 microns, potentially detecting young brown dwarfs down to a few MJupiter. Taken together, these two SIRTF datasets will offer a unique opportunity to take a census of the low mass/temperature members of the brown dwarf population.
