Mu Telescopii, Latinized from μ Telescopii is a solitary star in the southern constellation Telescopium. It has an apparent visual magnitude of 6.28, placing it near the limit of naked eye visibility. The object is relatively close at a distance of 118 light years but is receding with a heliocentric radial velocity of {{val|8.6|ul=km/s}}.
Mu Telescopii has a stellar classification of F5 V, indicating that it is an ordinary F-type main sequence star. It has been noted to be chromospherically active. The star is 2.12 billion years old with a current mass of {{val|1.28|ul=solar mass}}, and has a diameter 1.4 times that of the Sun It is radiating 3.22 times the luminosity of the Sun from its photosphere at an effective temperature of 6,570 K, giving a yellow white hue. Mu Telescopii is slightly metal deficient with an iron abundance 87% that of the Sun and spins with a projected rotational velocity of {{val|6.9|ul=km/s}}.
It has been observed for infrared excess suggesting the presence of a debris disk but so far, none has been found.
