The Who by Numbers Tour was a concert tour by the English rock band the Who, in support of their seventh album, The Who by Numbers (1975). It began on 3 October 1975, ended on 21 October 1976 and consisted of 79 concerts split between North America and Europe. Despite being named after The Who by Numbers, few songs from the album were actually performed during the tour.

The tour began with a European leg, which introduced the band's first use of a laser lighting display, and was followed by a North American leg that set indoor concert attendance records. The Who returned to America again in 1976 after playing several more shows in Europe, including three back-to-back Christmas shows at the Hammersmith Odeon, London. The opening 1976 US show in Boston came to an end when drummer Keith Moon collapsed on stage after playing only two songs. The following day he seriously injured himself and nearly bled to death. After performing at British football stadiums in May and June of 1976, the Who returned again to North America for the final of leg of concerts. Following their show in Miami, Moon was hospitalised for over a week. His erratic behavior worried the other band members who believed he would not be able to finish the tour. While Moon did manage to complete the tour, the final shows became his last public concerts before dying of a drug overdose in 1978.
