Abstract: We propose a nontrivial protocol to teleport a unknown $N$-qubit W-like state. The consumed resource is only $(N-1)$ shared ebits and $2(N-1)$ bits of classical communication, while the technique involves only controlled-NOT gates and single-qubit measurements/operations. The rule for reconstruction of the desired state at the receiving station is worked out explicitly in the most general case of an arbitrary $N\ge3$. The protocol is within the reach of present technologies.
