We have identified a quadruple system with two close eclipsing binaries inTESS data. The object is unresolved in Gaia and appears as a single source atparallax 1.08~$\pm$0.01 mas. Both binaries have observable primary andsecondary eclipses and were monitored throughout TESS Cycle 1 (sectors 1-13),falling within the TESS Continuous Viewing Zone. In one eclipsing binary (P =5.488 d), the smaller star is completely occluded by the larger star during thesecondary eclipse; in the other (P = 5.674 d) both eclipses are grazing. Usingthese data, spectroscopy, speckle photometry, SED analysis and evolutionarystellar tracks, we have constrained the masses and radii of the four stars inthe two eclipsing binaries. The Li I EW indicates an age of 10-50 Myr and, withan outer period of $858^{+7}_{-5}$ days, our analysis indicates this is one ofthe most compact young 2+2 quadruple systems known.
