Abstract: Let $α\in\r$ and let $\vec{v}\in\r^3$ be a unit vector. A singular minimal surface $Σ$ in Euclidean space is a surface $Σ$ whose mean curvature $H$ satisfies $H=α\frac{\langle N,\vec{v}\rangle}{\langle p,\vec{v}\rangle}$, where $N$ is the unit normal vector of $Σ$. In this short note we study singular minimal surfaces which are invariant by a one-parameter group of helicoidal motions. We prove that if $Σ$ is a helicoidal singular minimal surface, then the axis of the helicoidal motion is orthogonal to $\vec{v}$, $α=-1$ and $Σ$ is a circular right cylinder.
