The multicolour photometric observations of the neglected eclipsing binary FTUrsae Majoris (FT UMa) were obtained in 2010. The 2003 version ofWilson-Devinney code was used to analyze the light curves in $B$, $V$, and $R$bands simultaneously. Based on the spectroscopic mass ratio $q=0.984$ publishedby Pribulla et al., it is found that FT UMa is an evolved contact binary with acontact degree of 15.3%. The low amplitude of light variations, $\sim 0.15$mag, arises mainly from a moderately low inclination angle of $i=62.^{\circ}80$and almost identical components in size rather than the light dilution of athird component, which contributes light of only $\sim 10%$
