Samuel Sam Bockarie (2 October 1964 – 5 May 2003), widely known as Mosquito, was a Sierra Leonean politician and army commander who served as a leader of the Revolutionary United Front (RUF).

Sam Bockarie was born on 2 October 1964 in Koidu Town, Kono District in the Eastern Province of Sierra Leone.

From this time until Sankoh's release in 1999, Bockarie performed the task of director of military operations of the RUF, with alleged advice from Charles Taylor.

In January 1999, Bockarie along with AFRC commander Johnny Paul Koroma planned and made a devastating attack on Freetown, the capital of Sierra Leone.

However, tension continued in Sierra Leone, especially due to a new rebel faction called the West Side Boys, leading to more attacks in and around Freetown in May 2000.

During this time, Bockarie commanded his troops to attack civilian populations who he felt were supporting the government of Ahmad Tejan Kabbah, including the use of mutilation and sexual violence.

After fleeing Sierra Leone in 2000, Bockarie joined with Taylor's Anti-Terrorist Unit (ATU) in Liberia, (Bockarie moved to Liberia under an ECOWAS agreement with the then Sierra Leonean President) eventually moving to the Ivory Coast, where he participated in the rebellion led by Guillaume Soro in connection with the Gbatala base headed by Charles Taylor.

Under international pressure, Taylor initiated a policy of disengagement with regards to former RUF leaders, and officially expelled Bockarie from the country, although he was reported to have continued to travel freely between Liberia and Côte d'Ivoire.
