Sergeant Joseph "Joe" Griffin is the protagonist of Medal of Honor: Rising Sun.
Joseph was born in Mather, Pennsylvania. He was a star athlete during high school. After graduation, he joined the United States Marine Corps. Joseph was one of the few people worried about growing tensions with Japan and feared that a war may break out. He was scared that his younger brother, Donald Griffin, would also enlist. He tried to discourage him but Donald signed up anyway. Joseph was liked by everybody in his squad.
On December 7th, 1941. Joseph was stationed on the USS California. Early in the morning, he was woken up by the Japanese attack. He followed a fellow marine through the ship extinguishing fires and assisting crewmen. After giving the fire extinguisher to a cook Joseph quickly got topside. Once topside Jack Lauton gave him a BAR and Joseph joined the defenders. When one of the torpedoes hit, Joseph was thrown off deck by the blast. Luckily he was rescued by Jack, Francis Spinelli and Silas Whitfield in a PT Boat. Joseph manned the dual .50 cal turret on the boat and together they successfully fend off the attackers while escorting a ship to safety. Once they make it to shore the few marines cheer but Jack tells them to knock it off. The marines look at the bodies and sunken ships in the water, and pay respect to the men who were killed.
After Pearl Harbor Joseph was sent to Calumpis in the Philippines to stop the invading Japanese forces. He was assigned to his younger brother, Donald, and his demolition squad to blow up the Calumpis bridge to stop the Japanese forces. Unfortunately the truck containing the explosives is in the town square, behind enemy lines. With an M3 Stuart tank Griffin,Donnie and Gunny pushed their way to the church but before they could reach it they came across a blockade. Gunny ordered Griffin to find a way around it. Griffin made his way through the streets and the sewers ultimately reaching the church. He signaled the demolition team by using the church bell. Griffin jumped on the back of the demolition truck and fought off the incoming Japanese infantry while Gunny drove. As Griffin and Gunny make their escape in the truck, the tank that Donnie is in gets overrun by Japanese soldiers and is left behind. Once they escape Gunny comforts Griffin, telling him that his brother was a good marine.

- Griffin has no voice actor, thus, he is silent throughout the entire game. Shima acknowledges this when he asks "Nothing to say?" after Griffin doesn't respond to his question if he has a brother.
- He is a usable character in Medal of Honor Rising Sun`s multiplayer mode.
- In Medal of Honor: Heroes, Joseph Griffin is mistakenly referred to as a Corporal, despite being at least a Sergeant at the end of the war in Europe.
