Xabier Lizardi, or José María Aguirre Egaña (1896–1933) was a Spanish poet and writer in the Basque language.

His scarce work, focused mainly on only two books, Biotz-begietan ('In the heart and in the eye's) written in 1932 and the posthumous anthology Umezurtz-olerkiak ('Orphan Poems') published in 1934, in which he captures an intimate type of poetry.

In 1930 he participated in the Basque poetry contest in Errenteria, where he presented his poems Otartxo utsa ('The empty basket'), Paris'ko Txolarre ('The sparrow of Paris') and Agur ('Goodbye').

[4][5] In 1932 Lizardi published the book Biotz-Begietan ('In the heart and in the eyes') and was awarded the Kirikiño prize for the article Etxe barne bizia ('Life inside the house').

[7] The books Umezurtz-Olerkiak ('Orphan Poems') and Itz-Lauz ('In Plain Words') were published after his death as well as his dramatic works Ezkondu ezin ziteken mutilla ('The boy who could not marry') that appeared in Egan magazine in 1953.
