Watashi Wa was a Christian pop rock band from San Luis Obispo, California on Tooth & Nail Records. The name Watashi Wa is Japanese and roughly translated means, depending on the context, "I," "myself," or "As for me." Fans have speculated that this is a reference to the Biblical "I am", a phrase used throughout the Old and New Testament of the Bible by God and Jesus.

The band formed in 2000 when most of the members were still in their teens. They were first signed to indie label Bettie Rocket and released two albums before signing to Tooth & Nail in 2002.

The band broke up in July 2004, but in a deal with Tooth & Nail Records, singer/guitarist Seth Roberts' new band Eager Seas were signed to the same label and released their first album under the name Watashi Wa in 2006 before leaving the label.
