What Are the Biggest Law Firms in NYC? A Look at New York’s Legal Giants
When people search for the biggest law firms in NYC, they are usually talking about more than just the number of lawyers in an office. New York City is home to some of the most powerful and well-known law firms in the world, including firms that handle billion-dollar mergers, major securities disputes, private equity deals, international transactions, and high-profile litigation.
But there is an important distinction between biggest and most prestigious. A firm can have thousands of lawyers worldwide while another has a much smaller team but an enormous reputation in New York. Current 2026 rankings show both types of firms competing at the top of the NYC legal market.
So, if you are trying to understand which firms really dominate New York’s legal scene, here are some of the names worth knowing.
1. Kirkland & Ellis
Kirkland & Ellis official website is one of the world’s largest law firms by attorney headcount and revenue, with a substantial New York presence.

A 2026 attorney-count ranking places Kirkland first among firms by active New York attorneys, with more than 1,000 attorneys registered in New York.
Its sheer size makes it one of the clearest answers to the question of which firms are “biggest” in NYC.
2. Latham & Watkins
Latham & Watkins official website has a major New York operation and is another global heavyweight.
The firm handles corporate transactions, private equity, litigation, capital markets, tax, and other sophisticated matters.

Its practice includes mergers and acquisitions, private equity, litigation, investigations, antitrust, restructuring, and other high-stakes corporate matters.

Paul Weiss also remains one of the leading New York firms in major litigation and corporate work.
6. White & Case
White & Case official website has a particularly strong international presence.
Unlike some traditional New York firms that are closely associated with Wall Street corporate work, White & Case operates on a genuinely global scale, with lawyers handling cross-border transactions, disputes, project finance, international arbitration, and other matters.
The firm was listed with more than 600 active New York attorneys in a 2026 ranking.
For businesses operating across several countries, that international reach can be especially important.

The firm advises companies and financial institutions on mergers, acquisitions, securities, capital markets, banking, regulatory issues, and litigation.

Biggest Doesn’t Always Mean Most Prestigious
This is where the NYC legal market gets interesting.
If you measure size, firms such as Kirkland, Latham, Simpson Thacher, and Davis Polk stand out because of their large New York attorney populations.
But if you measure prestige, the list looks somewhat different.
Vault’s 2026-2027 rankings put:
- Cravath, Swaine & Moore
- Wachtell, Lipton, Rosen & Katz
- Skadden
- Latham & Watkins
- Sullivan & Cromwell
- Kirkland & Ellis
- Davis Polk
- Gibson Dunn
- Milbank
- Simpson Thacher
at the top of its national prestige ranking.
So a smaller firm can still be considered one of the most prestigious law firms in the country.
What About Cravath?
Cravath, Swaine & Moore official website deserves a special mention.
Cravath is not among the largest New York firms by raw attorney count. A 2026 ranking lists roughly 428 active New York attorneys.
Yet Vault ranks Cravath No. 1 in the United States for prestige for 2026-2027, making it a perfect example of why “biggest” and “most prestigious” should not be treated as the same thing.
Cravath has long been associated with high-end corporate transactions, litigation, and a demanding BigLaw environment.
What About Wachtell?
Wachtell, Lipton, Rosen & Katz official website is another fascinating example.
Wachtell has a relatively small attorney headcount compared with giant global firms, but its reputation in mergers and acquisitions, corporate governance, and high-stakes litigation is enormous.
Vault ranks Wachtell No. 2 nationally for prestige in 2026-2027, while its New York regional ranking places it at the top.
In other words, Wachtell does not need thousands of attorneys to be one of the most influential law firms in New York.
Why Are NYC Law Firms So Large?
New York is one of the world’s major financial and commercial centers.
Banks, investment firms, private equity companies, technology businesses, pharmaceutical companies, real estate developers, and multinational corporations all conduct business in the city.
That creates enormous demand for sophisticated legal services.
A single transaction might involve lawyers working on:
- Mergers and acquisitions
- Securities regulations
- Financing
- Tax
- Antitrust
- Employment
- Intellectual property
- Litigation
- International law
- Regulatory compliance
Large firms can bring many of those specialists together under one roof.
That is a major reason BigLaw has such a strong presence in New York.
How Much Do Lawyers at These Firms Make?
Compensation varies significantly by seniority, practice area, firm, and bonus structure.
Top BigLaw firms are known for paying substantially more than the average private-sector legal job, particularly to associates at the major New York firms.
But compensation is only part of the picture.
The hours can be demanding, deadlines can be intense, and expectations are high. Someone considering a career at one of these firms should look at the entire package rather than simply focusing on the headline salary.
