  Superconducting high entropy alloys (HEAs) are new members of disordered
superconductors. We report the synthesis and investigation of a new
superconducting high entropy alloy
Mo$_{0.11}$W$_{0.11}$V$_{0.11}$Re$_{0.34}$B$_{0.33}$ (MWVRB). It crystallized
in the tetragonal CuAl$_2$ crystal structure with space group (I4/$mcm$).
Comprehensive transport, magnetization and heat capacity measurements confirmed
bulk type-II superconductivity having transition temperature T$_{C}$ = 4.0 K.
The low temperature electronic specific heat suggests a fully gapped
superconducting state in weak coupling limit.
