Cholestasis was defined as conjugated bilirubin ≥30 μmol/L exceeding 20% of total level at least twice and graded as high if exceeding 100 μmol/L. Cholestatic cases were matched on gestational week with two non‐cholestatic controls.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The incidence rate of cholestasis was 37/250 (14.8%), with increasing rates in lower gestational weeks. Perinatal factors associated with cholestasis were pre‐eclampsia and being born small for gestational age. Cholestatic infants had three times more bronchopulmonary dysplasia and eight times more retinopathy of prematurity. The mortality was 13.5% in cholestatic infants versus 2.7% in controls (<jats:italic>P</jats:italic> = .040). All deceased cholestatic infants had high‐grade cholestasis. No surviving infants developed chronic liver disease by 10 years of age.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>Cholestasis was common in very preterm infants and linked to disease severity and adverse outcome. Cholestasis may be an independent risk factor for bronchopulmonary dysplasia and retinopathy of prematurity and more severe cholestasis associated with increased mortality. Cholestasis was not associated with chronic liver disease later in childhood.</jats:p></jats:sec>
