Celeron is a discontinued series of low-end IA-32 and x86-64 computer microprocessor models targeted at low-cost personal computers, manufactured by Intel. The first Celeron-branded CPU was introduced on April 15, 1998, and was based on the Pentium II.

Celeron-branded processors released from 2009 to 2023 are compatible with IA-32 software. They typically offer less performance per clock speed compared to flagship Intel CPU lines, such as the Pentium or Core brands. They often have less cache or intentionally disabled advanced features, with variable impact on performance. While some Celeron designs have achieved strong performance for their segment, the majority of the Celeron line has exhibited noticeably degraded performance.^[2] This has been the primary justification for the higher cost of other Intel CPU brands versus the Celeron range.^{[citation needed]}

In September 2022, Intel announced that the Celeron brand, along with Pentium, were to be replaced with the new "Intel Processor" branding for low-end processors in laptops from 2023 onwards.^[1] This applied to desktops using Celeron processors as well, and was discontinued around the same time laptops stopped using Celeron processors in favor of "Intel Processor" processors in 2023.
