"Questions 67 and 68" is a 1969 song written by Robert Lamm for the rock band Chicago (then known as Chicago Transit Authority) and recorded for their debut album Chicago Transit Authority. It was their first single release. Lead vocals are shared by Lamm and Peter Cetera.

The questions in "Questions 67 and 68" address the nature of a romantic relationship Lamm had during 1967 and 1968. The lyrics include the title phrase only as the last words.

Released in July 1969, the song peaked at number 71 on the US Billboard Hot 100 and 82 on the Cash Box Top 100. After the band's success with subsequent singles, "Questions 67 and 68" was edited to a more radio-friendly length and was re-released in September 1971, with "I'm a Man" as the B-side. The edited single climbed to number 24 on Billboard and 13 on Cash Box.

Cetera and Lamm recorded Japanese-language vocals for the song in 1971, and the version of the song with those vocals was released as a single in Japan. Columbia Records released the song only as a radio-only promotional 45 rpm single, with the English version on the other side. This recording was released digitally in 1998 on the Japan-only compilation CD The Heart Of Chicago 1967-1971 Volume II Special Edition (green cover), which also contains "Lowdown" sung in Japanese. The group performed the song live with the Japanese lyrics during tours of Japan in 1972, documented on the Live In Japan album, and again in 1995.

Panic! at the Disco sampled this song in "Hallelujah".
