洋即大洋，是地球海洋的主体，为海洋的中心部分。世界大洋的总面积约占海洋面积的89%。大洋的水深一般在3,000米以上，最深处可达1万多米。大洋离陆地远，不受陆地的影响，其水文和盐度的变化不大，每个大洋都有自己独特的洋流和潮汐系统。大洋的水透明度很大，水中的杂质少。世界上的大洋共有5个，按照面积由大到小分别为太平洋、大西洋、印度洋、南冰洋和北冰洋。海水覆蓋了地球約71%－72%的表面積（~3.6×108平方公里），可以分為數個主要的洋及一些較小的海。地球上97%的水都在海洋中，但海洋学者認為人類只探索了海洋中的5%。海洋的的總體積約13億立方公里（3.1億立方英里），平均深度約3,682米（12,080英尺）。海洋是地球水圈的主要成份，也是地球所有已知生命的起源，是碳循環之一，也影響氣候及天氣形態。海洋是23萬已知物種的棲地，而大部份的深海都尚未探索過。估計會有超過200萬種海洋物種。地球上海洋的起源目前尚不清楚，一般認為在冥古宙時就已存在，是生命起源的推動力。
