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. The firm maintains a strong tradition of training and promoting from within, producing a closely knit and collaborative community that considers excellence an expectation and achieving client objectives an imperative.

The firm was founded in 1967 by legendary trial lawyer Edward Bennett Williams. Our lawyers represent corporations (large and small), professional firms, governments, and individuals in a wide range of litigation, investigation, and arbitration matters.

The firm’s 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, our lawyers have 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.”

The firm’s robust intellectual property practice successfully represents clients in patent litigation matters worth billions of dollars. In the healthcare and consumer industries, Williams & Connolly serves 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. Our lawyers 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. Our lawyers also regularly appear before the Supreme Court and state and federal courts of appeals.

Known for our 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, Williams & Connolly is described by Chambers USA 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.”

Our distinctive approach to litigation has earned the firm top marks from leading publications and ranking services, such as ChambersLegal 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. The firm is also 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.

We hire the top graduates from the best law schools, and foster a culture that complements our focus on excellence – persistence, immersion in our clients’ businesses and industries, and a commitment to delivering results.



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.
