Jean-Baptiste-Alphonse Lusignan (27 September 1843 at Saint-Denis-sur-Richelieu, Canada East – 5 January 1893) was a French-Canadian writer.
He was educated at St-Hyacinthe College and studied theology there and at Montreal Seminary.
He contributed to several newspapers and was chief editor (1865–68) of Le Pays, the principal organ of the French-Canadian Liberal party at the time.
Lusignan published (1872), as a continuation of a similar work by Judge Ramsay, a "Digest of Reported cases"; "Coups d'oeil et coups de plume" (1884).
A leading francophone author, he was elected (1885) a member of the Royal Society of Canada.
