We report on the
high-resolution stellar parameters and
abundance analysis of the rapidly rotating post-AGB star IRAS 05381+1012. Analysis of high-resolution spectra shows that IRAS 05381+1012 has an effective temperature of 
K and a surface gravity of 
corresponding to
a spectral type G(2-3)I. These parameters result in an estimated
luminosity of 970 
and a distance of 2700 pc. We also
show that IRAS 05381+1012 has a projected rotational velocity 
km s-1. The abundance analysis based on a few
available lines reveals that this star is an iron-deficient
object with 
. We also analyze the abundance
pattern and compare it to other classes of stars with similar
stellar parameters.
