Ali
Hassan's father. Ali is a Hazara whom Baba's father took in when his parents were killed. He grew up alongside Baba just as Hassan did alongside Amir. Ali has a crippled leg and paralysis in his lower face muscles and the neighborhood children ridicule him. He is as devoted and loyal as his son. Ali is killed by a land mine when Hassan is already grown.
Amir
The story's narrator and protagonist. He is an Afghan man who had a privileged childhood in the Wazir Akbar Khan neighborhood of Kabul. The defining event in his life is his betrayal of his closest friend, Hassan. Amir lives in San Francisco from the age of eighteen. He returns to Afghanistan at the age of thirty-eight and ends up adopting Hassan's orphaned son, Sohrab.
Assef
A sociopath who worships Hitler. As a child, he is the neighborhood bully who rapes Hassan. As an adult, he is a Taliban official who delights in killing people. He keeps Sohrab as a sex slave until Amir comes to rescue him. After he beats Amir nearly to death, Assef loses an eye to Sohrab's slingshot. It is possible that Hosseini based the character of Assef on the reclusive one-eyed Taliban leader, Mullah Omar.
Baba
Amir's father. He is a wealthy and well-respected man with a dark secret; he had an affair with Ali's wife and Hassan is his illegitimate son. Baba wishes Amir were braver and stronger and that he could openly express his love for Hassan. Baba dies of terminal cancer in San Francisco shortly after Amir's wedding.
Farid
The Afghan man who drives Amir from Peshawar to Kabul and ends up helping him throughout his journey. He was injured fighting against the Soviets and is fiercely proud of his loyalty to Afghanistan. He saves Amir by taking him to a hospital in Pakistan.
General Taheri
Soraya's father. He is a former general who prefers collecting welfare to lowering himself to a blue collar job. He waits every day to be called back to Afghanistan.
Hassan
Amir's most loyal and devoted servant, who is born with a clept lip. He and Amir were nursed by the same woman and, unbeknownst to them both, they are half-brothers. Hassan is illiterate but smart and stands up for others. He is also the best kite runner in Kabul. He dies at the hands of the Taliban, defending Baba's house from takeover.
Khanum Taheri
Soraya's mother. She is a kind woman who likes to sing, although her husband does not let her. She became a hypochondriac after suffering a stroke and loves Amir all the more for listening to her describe her ailments.
Omar Faisal
A lawyer who counsels Amir that his best chance is to place Sohrab in an orphanage temporarily. He was raised in America but speaks perfect Farsi.
Rahim Khan
Baba's closest friend and Amir and Hassan's confidant. He has an uncanny way of knowing what people are thinking and how to speak to them. He is one of the few people who knows Hassan's real identity and about his rape. He encourages Amir to be a writer by giving him a notebook and it is he who summons Amir back to Afghanistan to atone for his and Baba's sins.
Raymond Andrews
The official at the American Embassy who urges Amir to give up trying to rescue Sohrab. Amir thinks he is cruel and does not understand wanting a child until the secretary tells him that Raymond Andrews's daughter committed suicide.
Sanaubar
Hassan's mother. She was Ali's notoriously beautiful first cousin and second wife, who ran off with a troupe of dancers. She refused to even hold Hassan when he was born. Years later, she returns to Wazir Akbar Khan to beg forgiveness from Hassan and ends up helping raise Sohrab. She dies peacefully when he is four.
Sofia Akrami
Amir's mother, who died in childbirth. She was a professor of literature at the university and her books inspire Amir to become a writer.
Sohrab
Hassan and Farzana's son. After his parents are murdered, he stays in an orphanage in Karteh-Seh. Then he is a sex slave to Assef until Amir rescues him. Sohrab tries to commit suicide after Amir tells him he may have to stay in an orphanage again. Eventually, Amir and Soraya bring him to America and adopt him.
Soraya
Amir's wife. She shamed her family as a young woman by running off with a man. She takes care of Baba when he is ill and eagerly accepts Sohrab into her family.
Wahid
Farid's brother. When Amir stays at his house, Wahid is kind to him and does not judge him for being American. He calls Amir "a true Afghan."
