All the magnetized planets in our solar system, including Earth, produce bright emission at low radio frequencies, predominantly originating in high magnetic latitudes and powered by auroral processes. It has long been speculated that similar radio emission may be detectable from exoplanets orbiting nearby stars, potentially providing the first direct confirmation of the presence, strength and extent of exoplanet magnetospheres, as well as informing on their role in shielding the atmospheres of potentially habitable exoplanets. Despite 4 decades of observations, no detection has been achieved. Surprisingly, however, brown dwarfs have been found to produce both radio and optical emissions that are strikingly similar to the auroral emissions from solar system planets, albeit 100,000 times more luminous.  I will discuss the radio emission from exoplanets and brown dwarfs with particular focus on ongoing searches with the OVRO-LWA, a low frequency radio astronomy array located in the Owens Valley, California, that simultaneously monitors 4000 nearby stellar systems in the search for radio emission from exoplanets.
