In this Letter we consider the magnetosphere–ionosphere (M–I) coupling at Jupiter‐like exoplanets with internal plasma sources such as volcanic moons, and we have determined the best candidates for detection of these radio emissions by estimating the maximum spectral flux density expected from planets orbiting stars within 25 pc using data listed in the NASA/IPAC/NExScI Star and Exoplanet Database (NStED). In total we identify 91 potential targets, of which 40 already host planets and 51 have stellar X‐ray luminosity over 100 times the solar value. In general, we find that higher planetary field strength, combined with larger rotation rate, higher stellar XUV luminosity and lower stellar wind dynamic pressure, results in higher radio power. The top two targets that host planets are ε Eri and HIP 85523, and the top two targets that have X‐ray luminosity over 100 times the solar value are CPD–28 332 and FF And.
