The Eastern Trans-Fly (or Oriomo Plateau) languages are a small independent family of Papuan languages spoken in the Oriomo Plateau to the west of the Fly River in New Guinea.

The languages constituted a branch of Stephen Wurm's 1970 Trans-Fly proposal, which he later incorporated into his 1975 expansion of the Trans–New Guinea family as part of a Trans-Fly – Bulaka River branch. They are retained as a family but removed from Trans–New Guinea in the classifications of Malcolm Ross and Timothy Usher.

Wurm had concluded that some of his purported Trans-Fly languages were not in the Trans–New Guinea family but rather heavily influenced by Trans–New Guinea languages. Ross (2005) removed the bulk of the languages, including Eastern Trans-Fly, from Wurm's Trans–New Guinea.

Timothy Usher links the four languages, which he calls Oriomo Plateau, to the Pahoturi languages and the Tabo language in an expanded Eastern Trans-Fly family.

• Meriam (within the national borders of Australia)
• Bine
• Wipi (Gidra)
• Gizrra

Oriomo (Eastern Trans-Fly) languages and respective demographic information listed by Evans (2018) are provided below.^[1] Geographical coordinates are also provided for each dialect (which are named after villages).^[2]

The pronouns Ross reconstructs for proto–Eastern Trans-Fly are,

I	*ka	exclusive we	*ki
		inclusive we	*mi
thou	*ma	you	*we
he/she/it	*tabV; *e	they	*tepi

There is a possibility of a connection here to Trans–New Guinea. If the inclusive pronoun is historically a second-person form, then there would appear to be i-ablaut for the plural: *ka~ki, **ma~mi, **tapa~tapi. This is similar to the ablaut reconstructed for TNG (*na~ni, *ga~gi). Although the pronouns themselves are dissimilar, ablaut is not likely to be borrowed. On the other hand, there is some formal resemblance to Austronesian pronouns (*(a)ku I, *(ka)mu you, *kita we inc., *(ka)mi we exc., *ia he/she/it; some archeological, cultural and linguistic evidence of Austronesian contact and settlement in the area exists (David et al., 2011; McNiven et al., 2011; McNiven et al., 2006; McNiven et al., 2004: 67-68; Mitchell 1995).

The following basic vocabulary words for Bine (Täti dialect), Bine (Sogal dialect), Gizra (Kupere dialect) and Wipi (Dorogori dialect) are from the Trans-New Guinea database.^[3] The equivalent words for Meriam Mir are also included.^[4]
