Lilias Eveline Armstrong (29 September 1882 – 9 December 1937) was an English phonetician who worked at University College London. Her father was James William Armstrong, a Free Methodist minister and her mother was Mary Elizabeth Armstrong, née Hunter. She graduated from the University of Leeds in 1908 and initially taught French at an elementary school in East Ham. She started working at UCL in 1918; she was appointed senior lecturer in 1921 and reader in 1936.
She married Simeon Karlovitch Boyanus (1871 – 1952) in 1926. He was a professor of English philology at the University of Leningrad and later became a lecturer in Russian at the UCL School of Slavonic and East European Studies.
Following a stroke, she died at Finchley Memorial Hospital, Middlesex at the age of 55.
Daniel Jones (1938:2) wrote in his obituary of her that she was one of the finest phoneticians in the world, and John Catford (1998:7) wrote that he thought her (1932) book was ″the best practical introduction to French phonetics.″
