We find the star HD 34700 to be a double-lined spectroscopic binary. We also identify it as a weak-line T Tauri object. The spectra of both components are very similar and both show the Li I feature at 6708Å. Strong arguments in favour of the binary nature of the star as opposed to other possibilities are offered. It is very likely that the companion is also a T Tauri star of similar mass. A projected rotational velocity, vsini, of 25 and 23km/s has been estimated for the blue and red components. We present a list of the lines identified and the radial velocities of the two components on three spectra obtained on consecutive nights.
