Interstate 787 (I-787) is an auxiliary Interstate Highway in the U.S. state of New York. I-787 is the main highway for those traveling into and out of downtown Albany. The southern terminus is at the toll plaza for New York State Thruway (I-87) exit 23 southwest of downtown Albany. The northern terminus of the route is unclear, with some sources placing the terminus at 8th Street in Troy, creating an overlap with New York State Route 7 (NY 7) between Green Island and Troy. Other documents show I-787 as terminating at its interchange with NY 7 and NY 787 in the town of Colonie. Regardless, the route is 10.16 miles (16.35 km) long if extended to Troy, or 9.55 miles (15.37 km) excluding the NY 7 overlap.

North of NY 7, the right-of-way of I-787 continues north as NY 787 to the city of Cohoes.

I-787 officially begins at the toll barrier for I-87/Thruway exit 23; however, a short 0.57-mile (0.92 km) spur between U.S. Route 9W (US 9W) and the interchange connecting I-787 to the Thruway, designated as NY 912S, an unsigned reference route, is signed as I-787. At the east end of the interchange (exit 1) with I-87, I-787 northbound merges with NY 912S, progressing due east for a short distance before curving to the northeast ahead of the Delaware and Hudson Railway mainline near exit 2 (NY 32). Past NY 32, I-787 parallels the Hudson River as it heads northward into the heart of downtown Albany, featuring a pair of exits with US 9 and US 20 at a massive interchange southeast of the Empire State Plaza on the west bank of the Hudson.
