Lucius Bruttius Quintius Crispinus was a Roman senator who lived in the second century AD. He was ordinary consul in 187, and Lucius Roscius Aelianus Paculus was his colleague.^[1]

Crispinus was a member of the Bruttia gens, who originated in Volceii, Lucania, Italy.^[2] His father was Gaius Bruttius Praesens, consul under Antoninus Pius; Olli Salomies suggests that his mother's name, which is otherwise unknown, was "Quintia" based on his nomen "Quintius", but Salomies has no further ideas about her identity.^[3] Crispinus' paternal grandparents were the consul and senator Gaius Bruttius Praesens, and Laberia Hostilia Crispina, the daughter of Manius Laberius Maximus.^[4] His sister was Bruttia Crispina, who married the Emperor Commodus.

He is generally thought to be the father of Gaius Bruttius Praesens, consul in 217.^[5]
