  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 6708 \AA. 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, $v$sin$i$, of 25 and 23 km/s$^{-1}$ 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.
