  We investigate classical rotating membranes in two different backgrounds.
First, we obtain membrane solution in $AdS_4\times S^7$ background, analogous
to the solution obtained by Hofman and Maldacena in the case of string theory.
We find a magnon type dispersion relation similar to that of Hofman and
Maldacena and to the one found by Dorey for the two spin case. In the appendix
of the paper, we consider membrane solutions in $AdS_7\times S^4$, which give
new relations between the conserved charges.
