Pinus resinosa, known as red pine (also Norway pine in Minnesota), is a pine native to North America.

Red pine is a coniferous evergreen tree characterized by tall, straight growth. It usually ranges from 20–35 metres (66–115 feet) in height and 1 m (3 ft 3 in) in trunk diameter, exceptionally reaching 43.77 m (143+1⁄2 ft) tall. The crown is conical, becoming a narrow rounded dome with age. The bark is thick and gray-brown at the base of the tree, but thin, flaky and bright orange-red in the upper crown; the tree's name derives from this distinctive character. Some red color may be seen in the fissures of the bark. The species is self pruning; there tend not to be dead branches on the trees, and older trees may have very long lengths of branchless trunk below the canopy.

The leaves are needle-like, dark yellow-green, in fascicles of two, 12–18 centimetres (4+3⁄4–7 inches) long, and brittle. The leaves snap cleanly when bent; this character, stated as diagnostic for red pine in some texts, is however shared by several other pine species. The cones are symmetrical ovoid, 4–6 cm (1+1⁄2–2+1⁄4 in) long by 2.5 cm (1 in) broad, and purple before maturity, ripening to nut-blue and opening to 4–5 cm (1+1⁄2–2 in) broad, the scales without a prickle and almost stalkless.
