34 Leonis Minoris (34 LMi), also known as HD 91365 or 11 H. Leonis Minoris is a solitary star located in the northern constellation Leo Minor. It is faintly visible to the naked eye as a white-hued point of light with an apparent magnitude of 5.58. Gaia DR3 parallax measurements imply a distance of 510 light-years, and it is currently receding with a poorly constrained heliocentric radial velocity of . At its current distance, 34 LMi's brightness is diminished by interstellar extinction of 0.16 magnitudes and it has an absolute magnitude of −1.02.
The object has received several stellar classifications over the years. Most sources generally agree that it is an early A-type main-sequence star with the classes ranging from A0 to A2. Anne Cowley and colleagues found that 34 LMi has broad or nebulous absorption lines in its spectrum, which could be a result of rapid rotation. However, D. R. Palmer gave a class of A0 IV, indicating that it is an evolved A-type subgiant. Richard O. Gray and Robert F. Garrison found a class of A1 III-IV, indicating that it has a luminosity class intermediate between a subgiant and giant star.
34 LMi has 2.4 times the mass of the Sun and an enlarged radius of . It radiates 323 times the luminosity of the Sun from its photosphere at an effective temperature of . At the age of 406 million years 34 LMi is 1.9% past its main sequence lifetime, meaning that it has evolved to the subgiant branch. The star has a near-solar metallicity at [Fe/H] = −0.03 (93% solar). Like many hot stars 34 LMi spins rapidly, having a projected rotational velocity of .
