Dick's Picks Volume 18 is a three-CD live album by the rock band the Grateful Dead. It was recorded on February 3, 1978, at the Dane County Coliseum in Madison, Wisconsin and on February 5, 1978, at the UNI-Dome in Cedar Falls, Iowa. There are also two songs from the February 4, 1978 show at the Milwaukee Auditorium in Milwaukee, Wisconsin. The album was released in June 2000.

Disc 1 combines songs from the February 3, 4, and 5 concerts in an order designed to simulate a first set of a Dead concert from that era. Disc 2 contains most of the second set plus the encore from the February 3 show. Disc 3 includes all of the second set from February 5.

This release is known to have a patched cut in the original soundboard tapes. If certain soundboards are missing parts of a song those creating the release will attempt to patch the cut if possible. Sometimes this is from an audience source or from an entirely different show. However, there is no database for these fixed soundboards and hence it is up to the listeners to stumble upon such a discovery. Track 4 on Disc 3, Truckin', contains a patch from the Truckin' recorded on 1978-01-31. The patch from 1978-01-31 starts at ~2:00 and ends at ~3:40 on the official release.
