Which one of the following Indian States has the longest coastline?

Gujarat has the longest coastline among all Indian states. According to historical data, its coastline was measured at approximately 1,214.7 km [1]. Recent revised data promulgated by the Ministry of Ports, Shipping and Waterways in 2025, based on Survey of India reports, has updated this length to 2,340.62 km due to more intricate measurement techniques [1]. This revision confirms that Gujarat retains its top position, followed by Tamil Nadu (1,068.69 km) and Andhra Pradesh (1,053.07 km) [1]. The total length of India's coastline, including islands, is approximately 7,516.6 km in older records and has been recalculated to over 11,000 km in recent updates [1]. Gujarat's extensive coastline along the Arabian Sea accounts for a significant portion of India's total mainland maritime boundary.
