Williams & Connolly is widely recognized as one of the nation’s premier litigation firms. Our lawyers routinely handle significant and complex civil, criminal, and administrative cases across the United States and around the globe. Williams & Connolly maintains a strong tradition of training and promoting its lawyers from within the firm, producing a closely knit and collaborative community that considers excellence an expectation and achieving client objectives an imperative.

Williams & Connolly was founded in 1967 by legendary trial lawyer Edward Bennett Williams. The firm represents corporations (large and small), professional firms, governments, and individuals in a wide range of litigation, investigation, and arbitration matters. Our robust intellectual property practice, for example, successfully represents clients in patent litigation matters worth billions of dollars. In the healthcare and consumer industries, we serve as national coordinating, trial, and/or resolution counsel for major pharmaceutical, medical device, pharmacy, technology, and consumer products companies in mass torts, multi-district litigation, and class actions. We litigate cross-border commercial and other disputes in wide-ranging international litigation and arbitrations. We have handled many of the most complex corporate, financial, and securities disputes stemming from the global financial crisis. We represent companies and individuals in government investigations and prosecutions of all types, including allegations of fraud, corruption, and FCPA violations. And firm lawyers regularly appear before the Supreme Court and state and federal courts of appeals.

Williams & Connolly is known for its ability to take cases to trial, and the deep bench of lawyers at the firm who have tried civil and criminal matters in courts across the country and internationally. Chambers USA describes the firm as “offering unmatched strength in depth and top-level trial capabilities,” and “[a] class act: a delight to litigate with, and fearsome to litigate against.” In addition, Washingtonian magazine has highlighted the firm’s “uncompromising emphasis on victory.”

Williams & Connolly’s corporate clients include major global companies from virtually every sector, including Pfizer, Sony, Samsung, Sprint, Intel, Bank of America, Google, The Carlyle Group, Medtronic, AstraZeneca, Genentech, Eli Lilly, News Corp/21st Century Fox, and HSBC. In addition, the firm has represented numerous law and accounting firms in professional liability and other matters, one reason why the Washington Post has recognized Williams & Connolly as the firm that other professional firms “turn to when they’re in trouble.”

Williams & Connolly’s distinctive approach to litigation has earned the firm top marks from leading publications and ranking services, such as Chambers, Legal 500, The National Law Journal, The American Lawyer, and Benchmark, both for overall litigation prowess as well as for many practice- or industry-specific types of litigation. Williams & Connolly also is known as an excellent and collaborative training ground for young litigators, providing clients with the highest-quality representation at every level of seniority and with a cohesive team always working to advance their interests. Vault consistently ranks Williams & Connolly among the most selective as well as among the best law firms to work for in the country; among the best in partner/ associate relations; and among the best for ensuring that young lawyers gain significant hands-on experience.

At Williams & Connolly, we believe that recruiting the very best talent and instilling cultural values that complement our focus on excellence–persistence, immersion in our clients’ businesses and industries, and a commitment to delivering value as our clients define it–continues to earn the confidence of informed decision makers and the privilege of helping them resolve the significant challenges they face.



It was during the week of January 15th, 1967 that Edward Bennett Williams, Paul Connolly, and Jeremiah Collins, along with a small team of associates, formed a new firm.
