Lacui Formation (Spanish: Formación Lacui) is a marine Miocene sedimentary formation located in Chiloé Island with minor outcrops near Carelmapu on the mainland.^[1]^[2] Gastropod shells are the most common macrofossils of Lacui Formation.^[2] According to Sernageomin (1998) the formation dates to the earliest Serravallian — that is the Middle Miocene.^[2]

South of Lacui Formation there are equivalent sedimentary rocks in the islands of Ipún, Lemo and Stoke.^[3]
