The Atmel AVR series of microcontrollers have it. In the AVRs it's called Two Wire Interface (TWI). Some of the most popular AVRs are ATMEGA8, ATMEGA 16, ATMEGA32, ATMEGA128.

You can also implement I2C in software. You can find plenty of examples if you search on this forum and on Google.

Hope this helps.

why not use PIC18f series thay have I2C modules present in them and u cann easily program them in C, using company provided softawre MPLAB
 

There are some 8051 based microcontrollers with hardware I2C. eg 89LPC933/4/5/6
Datasheet: **broken link removed**

Hope this helps.
