Chayanda field (also known as Chayandinskoye field; {{langx|ru|Чаяндинское месторождение}}) is a large hydrocarbon resource field, primarily of natural gas and gas condensates. It is located in the Lensky District of the Sakha Republic in Yakutiya.

The Chayanda field is located within the Nepa Arch oil and gas area of the central part of Nepa–Botuoba Anteclise in the southern part of the East Siberian Platform.{{cite news

In 2010, the resource in place (C1+C2 categories) was estimated at {{convert|1.24|e12m3|abbr=off}} of natural gas and 68.4 million ton of oil and gas condensates. As a result of the geological exploration in 2010–2011, reserves were increased by {{convert|251.3|e9m3|abbr=off}}. 86% of the natural gas in the field is methane. Up to 8% of the natural gas is nitrogen. The oil fractions contain heavy crude oil, tar and paraffin. In addition, there are {{convert|1.4|e9m3|abbr=off}} of helium reserves.
