  We hereby report a low-speed (about~21~km$\cdot$~s$^{-1}$ with respect to the
Sun) intruder member in the Hyades cluster based on the data in the literature.
The results show that the star is a non-native member star for the Hyades, with
its radial velocity being smaller than the radial velocity of the Hyades
cluster, even exceeding the standard deviation of the radial velocity of the
cluster by a factor of 9. Furthermore, by analyzing and comparing the orbits of
this star and its host, it may have intruded into its host in the past 2~Myr.
If the star's current motion orbit remains unchanged, it may leave its host in
the next 2~Myr. This implies that the intruder star may be temporarily residing
in the cluster. This study presents the first observational evidence of a star
intrusion into a cluster, which suggests that more evidence may be found.
