Ding Feng (died 271), courtesy name Chengyuan, was a Chinese military general and politician of the state of Eastern Wu during the Three Kingdoms period of China.

Ding Feng was from Anfeng County (安豐縣), Lujiang Commandery (廬江郡), which is in present-day Gushi County, Henan. He started his career as a soldier under the warlord Sun Quan sometime towards the end of the Han dynasty, and was commissioned as an officer for his courage in battle. He served as a subordinate of various generals under Sun Quan, including Gan Ning, Lu Xun and Pan Zhang. He fought in many wars for his lord and was well known for his valour. He was also wounded in battle several times and had slain many enemy commanders and captured the enemy's flags. He was promoted to Lieutenant-General (偏將軍) for his achievements.

In 252, Sun Liang succeeded his father Sun Quan as the emperor of the state of Eastern Wu. He appointed Ding Feng as Champion General (冠軍將軍) and enfeoffed him as a Marquis of a Chief Village (都亭侯).

In 252, Sima Shi, the regent of Wu's rival state Wei, sent Zhuge Dan and Hu Zun to lead the Wei armies to attack the Wu garrison at Dongxing (東興; southeast of present-day Chaohu City, Anhui). In response, the Wu regent Zhuge Ke led the Wu forces to resist the enemy, leading to the Battle of Dongxing between Wu and Wei.

The Wu generals said: "When the enemy learns that the Grand Tutor (Zhuge Ke) is coming here personally, they will surely retreat when we reach the shore." However, only Ding Feng had a different view: "No. They are making large movements in their territory. They are prepared, as they have mobilised large numbers of troops from Xuchang and Luoyang, so why would they go back empty-handed? Don't think that the enemy won't come. We should ready ourselves for battle." When Zhuge Ke reached Dongxing, he placed Ding Feng, Liu Zan (留贊), Lü Ju and Tang Zi in charge of the vanguard and they moved west along mountainous terrain. Ding Feng warned: "We are moving too slow. If the enemy seizes favourable ground, it will be harder to deal with them." He then led 3,000 soldiers with him, travelling on a different route from the main bulk of Wu forces.

Strong north winds were blowing at that time. Ding Feng and his 3,000 men reached the frontline within two days and seized control of Xu Embankment (徐塘). It was in winter and there was snowfall. The Wei officers were off guard and having a drinking session, so, despite the feeble size of his army, Ding Feng rallied his men and said: "Today is the day we claim titles and rewards!" He then ordered his troops to remove their armour and helmets, discard their jis and spears, and arm themselves with only shields and short weapons such as swords. The Wei soldiers laughed when they saw this event, and instead refused to ready themselves for combat. Ding Feng and his men fought bravely and destroyed the enemy camp at the front. Just then, another Wu force led by Lü Ju and a few others arrived, therefore joining Ding Feng in attacking the enemy camp. The Wei forces suffered a crushing a defeat.

Ding Feng was promoted to General Who Destroys Bandits (滅寇將軍) and had his marquis rank increased by one grade for his efforts in the battle.

In 255, the Cao Wei generals Guanqiu Jian and Wen Qin started a rebellion in the Wei-controlled Shouchun (壽春; present-day Shou County, Anhui). However, the revolt failed and Wen Qin fled towards Wu to seek refuge. Ding Feng was appointed as General of Tiger's Might (虎威將軍) and he followed an army led by the Wu regent Sun Jun to receive Wen Qin. They encountered Wei forces pursuing Wen Qin at Gaoting (高亭) and engaged the enemy in battle. Ding Feng, armed with a long spear and on horseback, led a charge into the enemy formation and they slew hundreds of Wei soldiers and seized much of the enemy's weapons and equipment. He was enfeoffed as the Marquis of Anfeng (安豐侯) for his achievements.
