HD 35929 is a pre-main-sequence Herbig Ae star candidate that exhibits emission in the Hα line and a weak IR excess. Although its luminosity type was estimated as IV from low-resolution spectroscopy, the insignificant HIPPARCOS parallax (0.88±0.93mas) contradicted the low luminosity. To resolve this discrepancy, we took 3 high-resolution optical spectra of the star (region 5200-6915Å, R∼60000) and used an archival one (4000-6800Å, R∼48000). Our analysis of the spectral and photometric information shows that HD 35929 is an F2 III star with T_eff=6880±100K, logg=3.3±0.1, logL/L_☉=1.7±0.2, vsini=70±5km/s, M=2.3±0.2M_☉, a mild metal deficit [Fe/H]=-0.2±0.1, and a weak interstellar reddening (A_V∼0.1mag) at a distance D = 345±60pc. These results confirm an earlier suggestion by Marconi et al. (2000A&A...355L..35M) that HD 35929 is located within the instability strip. At the same time, we argue that it is not a young object, but rather a post-main-sequence giant. The fundamental parameters and IR excess of HD 35929 are similar to those of HD19993, an emission-line late A-type giant recently discovered by us (Miroshnichenko et al., 1996ARep...40..509M). These objects might represent a group of evolved intermediate-mass stars with an enhanced mass loss.
