Optical/infrared photometric and spectrometric observations of the pre-main-sequence FU Ori object V1515 Cyg are presented. Data obtained indicate that this variable star has many features in common with other FU Orionis objects, including a variation of spectral type with wavelength of observation, strong 2.3 micron CO absorption bands, and a large infrared excess. The 1980 optical photometric minimum is interpreted as a dust condensation event in the outflowing wind of V1515 Cyg; the slow recovery from the minimum was caused by expansion of the dust cloud in the wind. It is suggested that dust formation occurred in material with a temperature of 500-700 K at a radial distance of (1-2) x 10 exp 15 cm from the mass-losing source. A mass-loss rate of (1-3) x 10 exp -5 solar masses per year can produce the conditions required for dust formation in the wind of V1515 Cyg.
