Maeda Toshinaga (前田 利長 Maeda Toshinaga, 1562 - 1614) was the eldest son of Maeda Toshiie and married one of Tokugawa Ieyasu's daughters.

He supported Ieyasu, and, after receiving his brother Toshimasa's lands (Noto, 215,000 koku), controlled a total of 1,250,000 koku, an amount exceeded only by the Shogunate. Toshinaga built and resided in Kanazawa Castle.

He had no children and adopted his brother Toshitsune as his heir.
