Interstate 787 (I-787) is an auxiliary Interstate Highway in the US state of New York. I-787 is the main highway for those traveling into and out of downtown Albany. The southern terminus is, per New York traffic data, at New York State Thruway (I-87) exit 23 southwest of downtown Albany. However, current signage indicates the terminus as along I-787's ramp to US Route 9W (US 9W). 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 unsigned NY 7 overlap.

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