Abstract
We report the first spectroscopic discovery of an extragalactic bona-fide T Tauri star. The object, LTS J054427-692659, is a low-mass, late-type star l ocated within the LMC dark cloud Hodge II 139. It shows H alpha emission wi th an equivalent width of 78 Angstrom, in line with galactic TTauri stars, but in excess of any main-sequence dwarf star. The only known plausible int erpretation of LTS J054427-692659 is a LMC TTauri star.
