We report the discovery of eclipses by circumstellar disc material associated with the young star PDS 110 in the Ori OB1a association using the SuperWASP and KELT surveys. PDS 110 (HD 290380, IRAS 05209-0107) is a rare Fe/Ge-type star, a ∼10 Myr-old accreting intermediatemass star showing strong infrared excess (LIR/Lbol ' 0.25). Two extremely similar eclipses with a depth of 30% and duration ∼25 days were observed in November 2008 and January 2011. We interpret the eclipses as caused by the same structure with an orbital period of 808 ± 2 days. Shearing over a single orbit rules o
