Ser Gwayne Hightower was a knight from House Hightower and an officer of the City Watch of King's Landing. He was the youngest son of Ser Otto Hightower and one of the brothers of Queen Alicent Hightower, the second wife of King Viserys I Targaryen.
In 111 AC, Gwayne participated in a tourney in King's Landing to celebrate the fifth anniversary of King Viserys I Targaryen's marriage to Gwayne's sister, Queen Alicent Hightower. Gwayne served as one of his sister's champions during the tourney, but he was unhorsed by Ser Criston Cole.
When the Dance of the Dragons began in 129 AC, Gwayne was named the second-in-command of the City Watch of King's Landing by his father, who instructed him to keep an eye on Ser Luthor Largent, the Commander of the City Watch, for any signs of disloyalty towards his nephew and the newly crowned King Aegon II Targaryen. Gwayne and Ser Arryk Cargyll were in the retinue of Grand Maester Orwyle when he traveled from King's Landing to Dragonstone in an unsuccessful attempt to reconcile Aegon II and his half-sister, Princess Rhaenyra Targaryen.
When King's Landing was attacked by the blacks in 130 AC, Gwayne rushed to the stables to sound the alarm, but he was seized, disarmed, and dragged before his own commander, Luthor Largent, who was still loyal to Prince Daemon Targaryen. When Gwayne denounced him as a turncloak, Ser Luthor drove his sword through Hightower's belly and ordered the city gates to be opened to the blacks.
