                                    The three major spiral galaxies in the Local Group are known to be
warped. The question is investigated of whether or not these three warps
are aligned. Using available HI observations we find that they are
noticeably aligned. Vectors defining the warp orientation form the
following angles: [M 31, M 33]=33°; [M 31, Milky Way]=35°; [M
33, Milky Way]=4°. The alignment of the directions of the warp lines
of nodes is lower even though also noticeable.
