Elk Estonian Aviation Company (, abbreviated ELK) was an Estonian airline which operated from 1991 to 2001.
In the beginning, ELK used three Tupolev Tu-154 jetliners; they later used Let L-410, BAe Jetstream 31 and Tupolev Tu-134A aircraft. The concern was later renamed ELK Airways.
On 23 November 2001, an ELK Antonov An-28 crashed into trees located shortly before the runway at Kärdla Airport, killing two passengers. The aircraft was being leased from Enimex.
