East Tsim Sha Tsui (Chinese: 尖東; Cantonese Yale: Jīmdūng) is a station of the Mass Transit Railway (MTR) system of Hong Kong.

At the time of opening, its southern terminus was the old Kowloon station located in Tsim Sha Tsui, where the Clock Tower stands today.

Plans for East Tsim Sha Tsui were subsequently revived in 1993 when the plans for East Kowloon line were modified to become a medium-capacity system as part of an Eastern Corridor with transfer to the Lantau Airport Railway (now Airport Express and Tung Chung line).

As a result of its underground location, the station was equipped with full-height platform screen doors, of the same type used on the KCR West Rail, which opened the year prior.

Upon the opening of the MTR Kowloon Southern Link on 16 August 2009, the East Rail line terminated in the south at Hung Hom again (albeit only temporary until the opening of Sha Tin to Central Link in 2022), and the tracks between Hung Hom and East Tsim Sha Tsui became part of the West Rail line.

In contrast, Octopus card users who transfer between East Tsim Sha Tsui and Tsim Sha Tsui stations within thirty minutes without making any other transport related purchases or more than nine non-transport related purchases in between stations are considered to have taken a single journey and are charged accordingly.
