Friday's draw at the All England Club pitched women's top seed Iga Swiatek against China's 33rd-ranked Zhu Lin, a potentially tricky first hurdle for the Pole.
Murray could face fifth seed Stefanos Tsitsipas in round two although first Tsitsipas must get passed former U.S. Open champion Dominic Thiem who has tumbled down the rankings.
Russian third seed Daniil Medvedev, a potential semi-final opponent for Alcaraz, returns to Wimbledon with a first round against British wildcard Arthur Fery.
The projected women's quarter-finals based on seedings would see Swiatek meet seventh seed Coco Gauff while third seed Rybakina could face Tunisia's Ons Jabeur.
Djokovic, bidding for a record-extending 24th Grand Slam title, will face Cachin on Monday while Rybakina plays the traditional Tuesday Centre Court opener for women's defending champions.
