The T-bills were priced to yield 2.0 percent, unchanged from a previous sale in September.
The sale's bid-cover ratio was 2.67, up from 2.5 in the previous sale.
The settlement date for Wednesday's auction will be October 10.
The amount raised included 262.5 million euros in non-competitive bids. Athens has a stock of about 15 billion euros of T-bills, which it regularly refinances.
