吞拿魚（中國大陸作金槍魚，香港作吞拿魚，台灣作鮪魚），是一種海水魚類，屬於鯖科下面的金槍魚族（學名：Thunnini）。本族包含5屬15種亞東魚^[2]，各物種之間大小變化很大，最小的亞東魚是圓舵鰹，其最大長度為50 cm（1.6呎），重量為1.8公斤（4磅）；最大的亞東魚則是北方藍鰭金槍魚，其最大長度為4.6米（15呎），重量為684公斤（1,508磅），平均長度為2米（6.6呎），據信其壽命可以長達50歲。

亞東魚、月魚屬以及鼠鯊目是目前僅存可將體溫維持在比周圍水體溫度高的物種。亞東魚是一種活躍而敏捷的食肉動物，該物種擁有光滑的流線型身體，也是游動速度最快的遠洋魚類之一；舉例，黃鰭金槍魚的游動速度可達75 km/h（47 mph）^[3]。亞東魚常在溫暖海域出現，故而成為一種大量商業捕撈的對象，也是釣魚活動當中的一種受歡迎魚類。然而，由於人類的過度捕撈，藍鰭金槍魚等部分亞東魚物種已深陷滅絕危機^[4]。

亞東魚的英語「tuna」衍生自古希臘語θύννος（thýnnos）的中世紀拉丁語格式Thunnus──而該詞又衍生自θύνω（thýnō），「匆忙、飛奔」之意^[5]^[6]。

然而，英文種「tuna」的直接來源為美洲西班牙語，並依序源自西班牙語「atún」、安達盧西亞阿拉伯語（英語：Andalusian Arabic）「at-tūn」（同化於阿拉伯語的التون‎，al-tūn，現代阿拉伯語為التن‎），然後再往前才是自上述提及之希臘語和拉丁文之來源^[7]。

鮪族為單系群演化支，包含5個屬及15個物種：

鯖科
- 鮪族：亞東魚
  - 細鰹屬：細鰹，英語稱細亞東魚（slender tuna）
  - 舵鰹屬：扁舵鰹，英語稱扁舵亞東魚（frigate tuna）
  - 巴鰹屬：巴鰹，英語稱小亞東魚（little tuna）
  - 鰹屬：正鰹，英語稱（skipjack tuna）
  - 金槍魚屬：長鰭亞東魚（albacore）、真亞東魚（true tuna）
    - 金槍魚亞屬：藍鰭亞東魚族群
    - 新金槍魚亞屬：黃鰭亞東魚族群

Estimated spawning stock biomass has declined approximately 85% over the past 36 years (1973–2009) and there is no sign that the spawning stock is rebuilding. It is therefore listed as Critically Endangered. Implementation of effective conservation and management measures are urgently needed."
