Over the last several years, discoveries of exceptionally bright gravitationally lensed dusty star-forming galaxies (DSFGs) at high redshift (z>1) have generated great excitement.  This is because these galaxies are bright enough to allow a variety of follow-up observations with the suite of submillimeter/millimeter/radio observing facilities that are now available.  Scientifically, what is particularly interesting is that these lensed DSFGs will enable us to examine individual star-forming regions on sub-kpc scales due to lensing magnification.  In this talk, I will review the development in this field with a special emphasis on our own project called the Herschel Lensing Survey (HLS).  Some of these lensed DSFGs are so bright that they are targeted by a few SOFIA Cycle 5 programs, and they will also serve as valuable targets for future infrared space observatories such as SPICA, which has been proposed as an ESA M5 mission.
