Dolichocolon, also known as redundant colon or tortuous colon, is the congenital presence of an abnormally-long large intestine.{{cite encyclopedia | doi-access= free | author-first1= Sonam | author-last1= Vadera | author-first2= Henry | author-last2= Knipe | author-first3= Mohammad Taghi | author-last3= Niknejad | author-first4= Daniel J. | author-last4= Bell | author-first5= Rohit | author-last5= Sharma | author-first6= Frank | author-last6= Gaillard | orig-date= First published 12 October 2021 | archive-url= https://web.archive.org/web/20240615045905/radiopaedia.org/articles/dolichocolon | archive-date= 2024-06-15 | url-status= live }} It should not be confused with an abnormally wide large intestine, which is called megacolon. The name originates from , and "colon".

Dolichocolon may predispose to abnormal rotation of the colon (volvulus) and its interposition between the diaphragm and the liver ( syndrome). The exact cause remains unknown.{{cite encyclopedia | editor-first1= Daisy | editor-last1= Warner | editor-first2= James | editor-last2= Sullivan | author-first= Caitlin | author-last= Geng | orig-date= First published 5 August 2022 | archive-url= https://web.archive.org/web/20250420073513/www.medicalnewstoday.com/articles/redundant-colon | archive-date= 2025-04-20 | url-status= live
