Site 45 at the Baikonur Cosmodrome is a launch site used by Zenit rockets. It has been the launch site for all Soviet and Russian government Zenit launches, along with a commercial launch conducted for Globalstar in 1998, and continuing commercial launches under the Land Launch programme. The main pad at the site is area 45/1, which was completed in 1983 following five years of construction. A second pad, area 45/2, was completed in 1990, but was destroyed by a launch failure in the same year.

The first launch from site 45, using pad 1, occurred on 13 April 1985. The last launch of a Zenit-3F took place on 26 December 2017.
