Celsius Network LLC is a bankrupt cryptocurrency lending company. Headquartered in Hoboken, New Jersey, Celsius maintained offices in four countries and operated globally. Users could deposit a range of cryptocurrency digital assets, including Bitcoin and Ethereum, into a Celsius wallet to earn a percentage yield, and could take out loans by pledging their cryptocurrencies as security. As of May 2022, the company had lent out $8 billion to clients and had almost $12 billion in assets under management.

In June 2022, the company gained notoriety when they indefinitely paused all transfers and withdrawals due to "extreme market conditions", resulting in steep declines in the price of bitcoin and other cryptocurrencies.

On July 13, 2022, Celsius filed for Chapter 11 bankruptcy.
