We report, for the first time to our knowledge, the existence of (1+1)-dimensional dipole solitons. We numerically find that such solitons can be supported by one-dimensional optical lattice in Kerr-type nonlinear media. Two dipoles of solitons are completely located at a broad optical lattice whose transverse modulation period is larger than ~1.5 times solitons width. The inherent repulsive interaction between dipoles can be effectively overcome by lattice. The stable swing motion of dipole solitons in such lattice is also demonstrated.
