Sunny Cove is a codename for a CPU microarchitecture developed by Intel, first released in September 2019. It succeeds the Palm Cove microarchitecture and is fabricated using Intel's 10 nm process node. The microarchitecture is implemented in 10th-generation Intel Core processors for mobile (codenamed Ice Lake) and third generation Xeon scalable server processors (codenamed Ice Lake-SP). 10th-generation Intel Core mobile processors were released in September 2019, while the Xeon server processors were released on April 6, 2021.

There are no desktop products featuring Sunny Cove. However, a variant named Cypress Cove is used for the 11th-generation Intel Core desktop processors (codenamed Rocket Lake). Cypress Cove is a version of the Sunny Cove microarchitecture backported to Intel's 14 nm process node.

The direct successor to the Sunny Cove microarchitecture is the Willow Cove microarchitecture, which powers the 11th-generation Intel Core mobile processors.
