Eliodoro Yáñez Ponce de León (May 6, 1860 – July 26, 1932) was a Chilean journalist, lawyer, and politician, and was one of the founders of La Nación newspaper.

Yáñez was born in Santiago, the son of Manuel Antonio Yañez Guerrero and of María Josefa Ponce de León.

[1] He soon became known as one of the most versed men around when it came to knowledge and interpretation of laws, and he also had very sound reasoning; the cases (cause) he won in court, where he was highly respected, are thanks to these qualities.

His unquestionable calling as a jurist led him to develop, along with Ricardo Passi Garcia, a Compilation of Current Laws and Decrees (1884), which was very well received.

Due to this, he was not only the editor of several printed media from that time, but he also performed a great contribution to the country by founding –along with senators Alfredo Escobar Campaña, Augusto Bruna Valenzuela and Abraham Silva- the La Nación newspaper, the first issue of which was published on January 14, 1917.
