Luilang, or ambiguously Ketagalan (Ketangalan, Tangalan; Chinese: 凱達格蘭語; pinyin: Kǎidágélányǔ), was a Formosan language spoken south of modern-day Taipei in northern Taiwan by one of several peoples that have been called Ketagalan. The language probably went extinct in the mid-20th century and it is very poorly attested.
