Dave Williams is an American politician from Colorado Springs, Colorado. A Republican, Williams represents Colorado House of Representatives District 15, which encompasses Colorado Springs and Cimarron Hills in El Paso County.

During the first year of his first term (2017), Williams introduced a bill (HB17-1134) titled the “Colorado Politician Accountability Act”. The bill was designed to crack down on sanctuary cities by allowing public officials of sanctuary cities who had not sought to overturn the local sanctuary law to be sued by citizens if an illegal alien committed a crime, and also by making elected officials of sanctuary jurisdictions liable to penalties for “rendering assistance to an illegal alien”. The bill was defeated in the House but Williams and two Senate co-sponsors reintroduced it with few changes in 2018 as HB18-1178.
