Eufemia Campos Cullamat[1] (born August 13, 1960), also known as Ka Femia, is a Filipina farmer, activist, and politician.

She co-authored the anti-endo bill seeking to give security of employment to workers by ending the practice of endo or labor contractualization.

[15][3] Cullamat has called for an end to mining and logging on ancestral lands, where Indigenous peoples are harassed and face displacement.

[16] On November 29, 2020, her youngest daughter Jevilyn Campos Cullamat died in an encounter with the 3rd Special Forces “Arrowhead” Battalion of the Philippine Army in Marihatag, Surigao Del Sur.

Antonio Parlade Jr. of the National Task Force to End Local Communist Armed Conflict alleged that Jevilyn's death is proof of Bayan Muna's role in recruiting the youth to the NPA.

The Makabayan bloc condemned the manner of the rebel's corpse after photographs were posted depicting what they say as Jevilyn's "obviously artificially posed body" along with confiscated paraphernalia.
