TOXMAP is a Geographic information system from the United States National Library of Medicine (NLM) that uses maps of the United States to help users visually explore data from the United States Environmental Protection Agency's (EPA) Toxics Release Inventory and Superfund Basic Research Programs.

TOXMAP helps users create nationwide, regional, or local area maps showing where TRI chemicals are released on-site into the air, water, and ground. It also identifies the releasing facilities, color-codes release amounts for a single year or year range, and provides multi-year aggregate chemical release data and trends over time, starting with 1987. Maps can also show locations of Superfund sites on the National Priority List (NPL), listing all chemical contaminants present at these sites. Users can search the system by location (such as city, state, or ZIP code), chemical name, chemical name fragment, release medium, release amount, facility name and ID, and can filter results to those residing within a pre-defined or custom geographic region. TOXMAP also overlays map data such as US Census population information, income figures from the Bureau of Economic Analysis, and health data from the National Cancer Institute and the National Center for Health Statistics.

The data shown in TOXMAP comes from:

* EPA Toxics Release Inventory (TRI)
* EPA Superfund Basic Research Program
* [ NLM Hazardous Substances Data Bank (HSDB)]
* [ NLM TOXLINE (Toxicology Bibliographic Information)]
* Agency for Toxic Substances and Disease Registry
* [ National Atlas of the United States of America (USGS)]
* [ NCI's SEER*Stat Database ]
* [ National Center for Health Statistics (NCHS)]
