2 Different Tears is the international extended play by South Korean girl group, the Wonder Girls. The title track was written and produced by J.Y. Park. It was simultaneously released on May 15, 2010 in English, Korean and Chinese. It was the first release to member Hyelim who replaced former member, Sunmi, after she departed from the group on February 2010. Also, EP contained 2009 English version of their number one single "Nobody".

"2 Different Tears" continues the retro theme of the Wonder Girls, including the 1980s inspired "Tell Me" and the 1960s, Motown-inspired "Nobody", by using a disco theme. The concept was created by Sohee and Yubin who describe it as a "more sophisticated and mature, modern feel." The music uses melodies similar to the Hustle. The lyrics speak about remembering a lost love.

Stylistically, the Wonder Girls used a retro 1980s denim look to promote the song as shown on the single cover and in the accompanying music video. The single release also included the English versions of previous singles "So Hot and "Tell Me" and as well as remixes of the title track and "Nobody". After the singles' release in Korea, the Wonder Girls embarked on their North American tour.

EP was released in United States for digital download via iTunes Store on May 15, 2010. Following day, it was released digitally worldwide and physically in South Korea. In June 2010, it was released physically in China and in August 2010 in Philippines through MCA Music and Universal Music Group. It was promoted with Wonder Girls World Tour.

The music video was directed by Jang Jae-hyeok, who had previously collaborated with the group on videos "Irony", "So Hot", and "Nobody". The video was filmed in Korean, English, and Chinese, and features cameo appearances by Bobby Lee and Park Jin-young. The video parodies the classic American television series Charlie's Angels. The group members wear 1980s inspired clothing, make-up and hairstyles.
