Divisoria (Tagalog: [dɪbɪˈsɔɾjɐ]) is a commercial sub-district along the districts of Tondo, Binondo, and San Nicolas in Manila, Philippines known for its mass market shops selling low-priced commodities; and for its diverse manufacturing activities. Tutuban Center is situated within the commercial hub along with a centrally located night market. The area has a variety of bazaars, bargain stalls and points of interest.

Divisoria is a term of Spanish origin, which translates as "divide" or "division." A variation of the term is línea divisoria, which translates as "dividing line." While the term can be used in the general sense of division, it can also be used with a geographical connotation.

This region was referred to as Divisoria due to its historical function dating back to the Spanish colonial period. That is, Divisoria "divided" Intramuros, the "gated city," from Parian, where the Chinese were racially segregated. It was after this division that the retail industry driven by Chinese merchants flourished, which led to the contemporary identity of Divisoria.

Divisoria is located in the districts of Tondo, Binondo, and San Nicolas in the Manila, thus part of the city's first, second, and third legislative districts. With no defined borders, Divisoria spans an area of about 0.5 square kilometers (0.19 sq mi) and is bisected by Recto Avenue. It has gained a reputation for its poorly sanitized streets and poor-quality products but with the establishment of the Tutuban Centermall in 1993, the area saw the rise of other shopping malls that attracted by those from the higher classes.

Divisoria is known for its dimly lit streets and "fly-by-night" vendors. In response to commercial traffic and crime occurrences, Manila Mayor Joseph Estrada installed 137 new lamp posts along Benavidez and Asuncion Streets in the area.

The market's reputation for poor sanitation has brought attention for further research, particularly the currencies circulating around it as well as its vegetables. Sampled in a study, parasitic contamination of coins and paper bills obtained from selected public markets in Metro Manila has been reported. Furthermore, vegetable samples were obtained from Divisoria and other markets from Quezon City and Muntinlupa. The prevalence of parasitic infestation of the samples was 45%. According to the study, other public markets obtained their vegetables from Divisoria. Both studied recommended extra caution to safeguard oneself from possible causes of infections.

On July 23, 2004, the SAI Building at Divisoria collapsed. Having stood for five years at eight stories high, the building was located at the intersection of Padre Rada and Juan Luna streets. While there were no injuries or fatalities, there were cases on property damage. This incident entails that the National Building Code is not being strictly enforced.

According to Harry Wong, the construction engineer of SAI Building, the projected durability of the building was 10 years. However, the foundation of the building weakened due to simultaneous construction in the north side and across the building.
