<jats:title>Abstract</jats:title><jats:p>Herein, the direct electrochemistry of bilirubin oxidase from <jats:italic>Magnaporthe orizae</jats:italic> (<jats:italic>Mo</jats:italic>BOD) was studied on CNTs functionalized by electrografting several types of diazonium salts. The functionalization induces favorable or unfavorable orientation of <jats:italic>Mo</jats:italic>BOD, the latter being compared to the well‐known BOD from <jats:italic>Myrothecium verrucaria</jats:italic> (<jats:italic>Mv</jats:italic>BOD). On the same nanostructured electrodes, <jats:italic>Mo</jats:italic>BOD can surpass <jats:italic>Mv</jats:italic>BOD in terms of both current densities and minimal overpotentials. Added to the fact that <jats:italic>Mo</jats:italic>BOD is also highly active at the gas‐diffusion electrode (GDE), these findings make <jats:italic>Mo</jats:italic>BOD one of the MCOs with the highest catalytic activity towards the oxygen reduction reaction (ORR).</jats:p>
