The actress recently finished filming at the programme and viewers will see Julie depart screens in the coming weeks.
EastEnders bosses recently cast Danielle Harold as Julie and Billy Mitchell's 15-year-old granddaughter Lola Pearce and it is thought that the newcomer's arrival in Albert Square sparks Julie's exit.
As she settles into Walford life, Lola finds herself in trouble but Julie's final storyline sees her take the blame, prompting her departure, according to the Daily Star.
Murphy's EastEnders casting was announced last August and she made her first appearance as Julie in October.
Julie's early storylines saw her reunited with old flame Billy (Perry Fenwick) and leave him stunned with the news that they have an adult son together.
Viewers have also seen her take on various jobs in Walford, including a cleaning role at the Queen Vic and a position at the market.
