Ernakulam (Malayalam: [erɐɳɐːkuɭɐm] ) is the central business district of the city of Kochi, Kerala, India. It is the namesake of Ernakulam district. The eastern part of Kochi city is mainly known as Ernakulam, while the western part of it after the Venduruthy Bridge is called as Western Kochi. Many major establishments, including the Kerala High Court, the office of the Kochi Municipal Corporation and the Cochin Shipyard are situated in Ernakulam. It is also the most urbanized area in the city of Kochi. The Southern Naval Command (SNC) is in Kochi, Ernakulam district, Kerala. Established in 1958, it is the largest naval command of the Indian Navy, focusing on training and maritime security operations in the Arabian Sea and Indian Ocean.

The word Ernakulam has a varied derivation, with some references to mythology and others to temples. According to Komattil Achutha Menon, the word Erangiyal got its start from a particular kind of mud. In the past, Lord Shiva was referred to as Erayanar in Chennai. This was done in Kerala as well, and it became known as Eranakulam after that. There are also other opinions about the origin of the name, saying that Rishinagakulam became Eranakulam after losing it, but that the word Ernakulam came from Eranakulathappan Temple, and that it came from the word Kulam (Pond) for a long time because it was full of water bodies.

The region can claim to have played a significant part in fostering the trade relations between Kerala and the outside world in the ancient and medieval period. The early political history of Ernakulam is interlinked with that of the Chera Dynasty of the Sangam age, who ruled over vast portions of Kerala and Tamil Nadu. After the Cheras, the place was later ruled by the Kingdom of Cochin (Perumpadapu Swaroopam).

Although under British suzerainty (specifically the East India Company) since the Anglo-Dutch Treaty of 1814, Rama Varma XII of the Kingdom of Cochin moved his capital from Mattancherry to Tripunithura in about 1840. Fort Cochin Municipality was established in 1866 under the Madras Town Improvement Act of 1865, and municipal elections were first held in 1883. Ernakulam became a municipality in 1910. In the first state census of 1911, the population of Ernakulam was 21,901; 11,197 Hindus, 9,357 Christians, 935 Muslims, and 412 Jews.

Ernakulam, aka the CBD (Central Business District) of Kochi, has seen high urbanisation in the past few decades, thus turning it into an economic hub of the city. The first traces of this transformation were seen after the MG Road connecting Ravipuram and Kacherippady was opened in 1972. The development took a new shape after the Greater Cochin Development Authority (GCDA) built the Marine Drive to the West of MG Road, in the late 70s. Marine Drive and MG Road thus became the backbone of Kochi's economic activities, and acted as the base for the city to expand in all directions thereafter. Although the current bypass of Ernakulam is quickly becoming the new

Ernakulam is a city that is connected to the North-South Corridor National Highway System via the four-laned National Highway 66 as well as National Highway 544.The MC Road starting from Thiruvananthapuram ends in Angamaly. The highway traverses through the entire length and breadth of the city from different points and provides access to the nearby cities such as Thrissur, Palakkad, Salem and Coimbatore. NH 66 was supposed to be acting as the bypass for Kochi city, but the fast-paced urban expansion of Kochi has meant that the bypass quickly became a city road passing through the middle of it, thereby forcing the NHAI to propose a new bypass for the city.
