contents We show that every cycle in the degree $d$ algebraic cobordism group $Ω_d(X)$ of a smooth projective variety $X$ over a field of characteristic $0$ is smoothable when $2d<\dim(X)$, that is, it can be written as a linear combination of cycles represented by smooth closed subvarieties of $X$. This generalizes a result of Kollár and Voisin from Chow groups to algebraic cobordism groups.
