NEMA, also known as Tenth and Market, is a 754-unit luxury residential apartment complex in the Mid-Market neighborhood of San Francisco, California, United States, across the street from Twitter's corporate headquarters.

[6] Originally designed by Heller Manus as 719 residential condominiums,[7] the project site was cleared for development in 2007.

Due to the financial crisis of 2007–2008, developer Crescent Heights converted the project to apartments,[8] but the site remained a vacant hole in the ground for four years.

[15][16] In 2016, NEMA sponsored an interactive art project entitled "Wall of Good Looks" along Market Street.

[17] Designed by Handel Architects, NEMA's four linked apartment building towers range from 10 to 37 stories high.
