The Mander is a river in the Reach which flows past Highgarden, the seat of House Tyrell. It is the longest and broadest river in the Seven Kingdoms. The Tyrells include Lord Paramount of the Mander among their titles.

Part of the Reach proper, the Mander has its source in hills near Tumbleton in the northeastern Reach near King's Landing. The river flows southwest past Bitterbridge, where it is crossed by the roseroad. After Bitterbridge, the Mander meets the Blueburn near Longtable and then the Cockleswent near Cider Hall. Near Highgarden the Mander meets an as-yet-unnamed river which flows south from Goldengrove. From Highgarden the Mander continues west to a bay of the Sunset Sea near the Shield Islands.
Whilst large and powerful, the Mander is a slow-moving river, wide with snags and sandbars to trap the unwary ship. The upper reaches of the Mander are muddy and rough, and only shallow-draughted boats can go as far as Bitterbridge. As they near Highgarden, they settle down and become clear and calm, and are navigable by seagoing vessels.
According to legend, Garth the Gardener built Highgarden atop a hill along the Mander. John II Gardener, King of the Reach, sailed his barge to the river's headwaters, receiving homage from lords and petty kings during his voyage. The Mander was considered part of the Reach proper.
The headwaters of the Mander were conquered by Arlan I Durrandon, a Storm King, but they were eventually lost by the descendants of his grandson, Arlan III. A Dornish king once sacked Highgarden after crossing the Mander.
House Manderly once lived at Dunstonbury and held rich lands along the Mander, but they were driven away by Lord Lorimar Peake at the behest of King Perceon III Gardener. Despite being exiled, the Manderlys still claim the title Lord Marshal of the Mander.
The Mander was said to have been red with blood for twenty leagues after the battle at Stonebridge, part of the Faith Militant uprising. According to legend, Septon Mattheus encountered Septon Barth at Bitterbridge in 50 AC during their respective journeys to Oldtown and King's Landing.
Ser Rickard Thorne was slain while crossing the Mander at Bitterbridge during the Dance of the Dragons, and Prince Maelor Targaryen was killed shortly after. Many townspeople drowned in the river during the retaliatory sack of Bitterbridge by the greens.
At a crossing of the Mander during the First Blackfyre Rebellion, Ser Quentyn Ball slew all of Lady Penrose's sons except for the youngest, whom he spared as a favor to the lady. The Blackwater Rush and the Mander ran low during the terrible summer drought of 211 AC.
A Clash of Kings
During the War of the Five Kings, Renly Baratheon sets his sprawling camp where the roseroad crosses the Mander near Bitterbridge. Men of the Reach set up their pavilions north of the river, and the storm lords establish themselves on the southern bank. Catelyn Stark sees the muddy waters of the Mander when she arrives at the melee at Bitterbridge.
A Storm of Swords
A Feast for Crows
Euron Greyjoy, the new King of the Isles and the North, sends Torwold Browntooth and the Red Oarsman up the Mander with a dozen longships to draw away the lords of the Shield Islands.
