Abstract: We present the discovery of three small planets transiting K2-136 (LP 358 348, EPIC 247589423), a late K dwarf in the Hyades. The planets have orbital periods of 7.9757 ± 0.0011, {17.30681}<SUB>-0.00036</SUB><SUP>+0.00034</SUP>, and {25.5715}<SUB>-0.0040</SUB><SUP>+0.0038</SUP> {days}, and radii of 1.05 ± 0.16, 3.14 ± 0.36, and {1.55}<SUB>-0.21</SUB><SUP>+0.24</SUP> {R}<SUB>\oplus </SUB>, respectively. With an age of 600-800 Myr, these planets are some of the smallest and youngest transiting planets known. Due to the relatively bright (J = 9.1) host star, the planets are compelling targets for future characterization via radial velocity mass measurements and transmission spectroscopy. As the first known star with multiple transiting planets in a cluster, the system should be helpful for testing theories of planet formation and migration.
