'''Seco-LSD''' is an analogue of LSD with one or more bonds removed and may refer to:

* 3,5-Seco-LSD (also known as DEIMDHPCA) * 8,10-Seco-LSD (also known as NDTDI) * 10,11-Seco-LSD

Additional seco-LSD compounds with more bonds (and atoms) removed include DEMPDHPCA, ''N''-DEAOP-NMT, and ''N''-DEAOP-NMPEA.
