λ Pictoris, Latinised as Lambda Pictoris, is a solitary, orange-hued star in the southern constellation of Pictor. It is visible to the naked eye, having an apparent visual magnitude of +5.29. With an annual parallax shift of 8.71 mas as seen from the Earth, it is located around 374 light-years from the Sun. At the estimated age of 2.24 billion years old, it is an evolved K-type giant star with a stellar classification of K0/1 III. Lambda Pictoris has 2.2 times the mass of the Sun and is radiating 112 times the Sun's luminosity from its photosphere at an effective temperature of {{val|4581|ul=K|fmt=commas}}.
