Isha Lanla Dyfan (born 1955) is a Sierra Leonean lawyer who became the United Nation's Independent Expert on the Situation of Human Rights in Somalia in 2020.

She has previously worked for the United Nations–African Union Mission in Darfur and Amnesty International.

She was also accepted in Sierra Leone and she practiced law for over twelve years there until the civil war made her leave for America.

During that time Dyfan, fellow lawyer Yasmin Jusu-Sheriff and Patricia Kabbah worked with groups like the Mano River Women's Peace Network to ensure that wider international community were aware of the abuses that were taking place in Sierra Leone.

She supported the government's plans but urged them to deal with gender based violence.
