Aims.We investigate the origin of the ${\rm Br}\gamma$ emission 
 of the Herbig Ae star HD 104237 on Astronomical Unit (AU) scales.
        Methods.Using AMBER/VLTI at a spectral resolution $\mathcal{R}=1500$ we 
 spatially resolve the emission in both the ${\rm Br}\gamma$ line 
 and the adjacent continuum.
        Results.The visibility does not vary between the continuum and the ${\rm Br}\gamma$ line, 
 even though the line is strongly detected in the spectrum, with a peak 
 intensity 35% above the continuum. This demonstrates that the line and
 continuum emission have similar size scales. We assume that the K-band
 continuum excess originates in a “puffed-up” inner rim of the 
 circumstellar disk, and discuss the likely origin of ${\rm Br}\gamma$.
        Conclusions.We conclude that this emission most likely arises from a compact 
 disk wind, launched from a region 0.2–0.5 AU from the star, with a spatial extent similar to that of the near infrared continuum emission region, i.e., very close to the inner rim location
