Lourdes "Chit" Panganiban Estella-Simbulan (August 19, 1957 – May 13, 2011) was a Filipino journalist[1] and professor,[2] known for her critical writings on government repression, abuse, corruption and human rights violations.

[5] In recognition of her early work, as a journalist during the Philippines' Martial Law period under Ferdinand Marcos, Estella-Simbulan's name was one of 19 added in November 2016 to the inscriptions on the Bantayog ng mga Bayani (Monument of the Heroes) Memorial Wall, which is dedicated to individuals who "defied risks and dedicated their life for the cause of truth, justice, peace and freedom for the Filipino people" during the Marcos regime.

She later wrote articles for anti-dictatorship groups, such as the National Secretariat for Social Action (NASSA) of the Catholic Bishops' Conference of the Philippines (CBCP).

[3] Estella became a reporter for the Manila Evening Post and Tempo, before she joined Ang Pahayagang Malaya, an independent newspaper where she covered news at the Malacañan.

[11] A libel suit filed by Estrada against the Manila Times forced the paper to issue a front-page apology, which led Estella and fellow editors Booma Cruz, Joel Gaborni, and Ed Lingao to resign in protest.

[18] The first lecture was about the human rights situation in the Philippines, delivered by Satur Ocampo, who is a veteran journalist, former political prisoner and representative in Congress.
