Dallas County Republicans United PAC, also known as DCR United, is a volunteer-staffed political action committee founded by Jennifer Stoddard Hajdu, Susan Fountain, and Bill Anderton. The organization aims to bring conservatives together and support Republican candidates, with a particular focus on local City Council and School Board elections across Dallas County. It describes itself as a 501(c)(4) organization with no salaries or overhead, and says it commits all funds received to increasing conservative leadership.

DCR United invites Dallas County conservatives to join, stay informed, and participate in its activities. Through its website, supporters can sign up for email and text updates, make donations, contact the organization through online conversations, and follow its social media accounts. The site also publishes commentary, reporting, event information, and articles on elections, conventions, precinct leadership, and political news. It republishes earlier work by team members and features newer posts, offering supporters a channel for ongoing political engagement and information about Republican activities in Dallas County and Texas.
