We report results of photometric monitoring of the NGC 2243 field in V and I filters. Two W UMa-type systems and three detached eclipsing binaries were discovered. Both contact systems are likely members of the cluster. One of the detached binaries - variable V₁ - has a period P=1.188 day. This variable is located at the cluster's turnoff in the color-magnitude diagram. Determination of parameters for components of V₁ can provide direct information about properties of turnoff stars in NGC 2243 as well as to allow direct determination of cluster's distance. A background RR Lyr variable was found in the monitored field. The reddening of NGC 2243 is estimated at E(V-I)=0.10±0.04 based on the V-I color exhibited by this star at minimum light. The observed distribution of colors for the background halo stars shows a cutoff at (V-I)≃0.60 what implies E(V-I)≤0.12 for the cluster.
