The British Committee for Universities of Palestine says in an open letter to John that it is wrong to perform in Israel because of alleged abuses committed during the Israeli military campaign in the Gaza Strip last year.
A spokesman for the singer did not respond to a request for comment Tuesday.
The committee's letter says John cannot be morally neutral in the conflict between the Palestinians and the Israelis.
John is scheduled to play at a Tel Aviv stadium on June 17. Other major stars including Paul McCartney and Madonna have played in Israel in recent years.
