The men's C-1 1000 metres event was an open-style, individual canoeing event conducted as part of the Canoeing at the 1964 Summer Olympics programme on Lake Sagami, Japan.
The preliminary heats were held on 20 October 1964; 11 competitors entered and were split into two heats of 6 and 5 canoeists. The top three placers in each heat advanced to the final, while the remaining five entrants had to compete in a semifinal held the next day. The 2 slowest canoeists were eliminated in the semifinal on 21 October, with the top 3 joining the initial 6 finalists. The final was held on 22 October, following the 2 individual kayaking event finals but preceding the 4 pairs and fours events.
Top three in each heat move on to final, all others relegated to semifinal.
