About Billy Coyle

Billy Coyle

Oklahoma City Criminal Defense Attorney | Founder, Billy Coyle Law Firm

Billy Coyle has spent his entire career fighting for the rights of Oklahomans. A seasoned criminal defense attorney with nearly three decades of courtroom experience, Billy is known for his fearless advocacy, strategic thinking, and deep understanding of both state and federal law.

A lifelong Oklahoma City resident, Billy began his legal career as a prosecutor—an experience that now gives him a critical edge in defending his clients. He has handled thousands of cases, from DUIs and drug charges to complex white-collar crimes and high-stakes federal indictments. No matter the charge, Billy brings the same level of preparation, grit, and commitment to every case.

He believes every client deserves to be heard, respected, and vigorously defended. That’s why he’s built a firm that’s focused on real people, real solutions, and real results.

When he’s not in the courtroom, Billy is active in the Oklahoma legal community and passionate about protecting constitutional rights.  When not fighting for your rights he enjoys hunting, and spending time with his family.

Today Billy leads Billy Coyle Law Firm from our office at 125 Park Ave #100 in downtown Oklahoma City, a short walk from the Oklahoma County Courthouse. He represents clients in Oklahoma County District Court, Oklahoma City Municipal Court and the U.S. District Court for the Western District of Oklahoma, as well as in courts across the state.
