We have measured the differential Stark shift in the 6<i>s</i>6<i>p</i><sup>3</sup><i>P</i><sub>1</sub> state of mercury. The technique we used was to measure the shift in the magnetic-field level crossing in <sup>199</sup>Hg when an additional electric field was applied. We obtained the value <i>E</i>(<i>m<sub>J</sub></i>=±1) - <i>E</i>(<i>m<sub>J</sub></i>=0) =-2.367±0.024 kHz/(kV/cm)<sup>2</sup>. ∊<sup>2</sup>, where ∊ is the electric field.
