犁鳍柠檬鲨学名Negaprion acutidens),又名尖齿柠檬鲨犁鳍柠檬鲛,简称柠檬鲨(但和美洲同属的柠檬鲨非同种),为真鲨科柠檬鲨属下的一个种。主要分布在印度洋-太平洋海域深度低于 92米(302英尺) 的亚热带及热带浅海地区,栖息地包括红树林河口珊瑚礁等。体长可达 3.8米(12英尺),为胎生,在 10~11 个月的妊娠期后每两年可产下最多 13 头幼鲨。

犁鳍柠檬鲨是以硬骨鱼为食的掠食者,不常进行长距离的移动,时常可以在固定地点重复目击到同一个体。这项习性加上牠们的低繁殖率导致犁鳍柠檬鲨在印度东南亚海域的个体数量大减甚至是局部地区灭绝。人类会为了肉、鱼翅鲨鱼鱼肝油英语shark liver oil捕捉牠们。
