I study the $x$-distribution of the orbital angular momentum (OAM) of quarks and gluons in the nucleon with particular emphasis on the small-x region. I argue, in two different ways, that the gluon OAM significantly cancels the gluon helicity distribution at small-$x$. A similar cancellation occurs also in the quark sector.
