Brobeck, Phleger & Harrison LLP was a large law firm based in San Francisco, California, United States.

In 2003, the firm was liquidated under Chapter 7 of the U.S. Bankruptcy Code, after it had lost a substantial amount of money in the dot-com bubble and merger talks with Morgan, Lewis & Bockius had fallen through.

Between the two World Wars, the firm cultivated an A-list of bluechip San Francisco clients, including Wells Fargo, and managing partner Herman Phleger served as an advisor to Bernard Baruch during the creation of the United Nations.

By the mid-1990s, Brobeck had become one of the two largest firms representing technology startups in Silicon Valley,[3] with marquee clients such as Cisco Systems, Sun Microsystems, Nokia and Nike.

Overwhelmed by partner defections, bank debt, and loads of empty office space, Brobeck announced that it was disbanding two days later.
