Twice-divorced Harrison is said to have been reluctant to walk down the aisle for a third time, but has now told Calista - his girlfriend of six years - he is ready to tie the knot.
A source told National Enquirer magazine: "He said he would marry Calista as soon as he's finished with the promotional work for the new 'Indiana Jones' movie - and Calista is holding him to his promise."
The couple are believed to be planning a low-key ceremony, which is expected to be attended by family and close friends.
Harrison, 65, started dating 43-year-old Calista after they met at the Golden Globe awards in 2002.
As well as his four children from his previous marriages, Harrison has helped the 'Brothers and Sisters' actress raise her seven-year-old adopted son Liam.
The actor hopes to adopt Liam, but Calista told him they must marry first.
A source said: "Harrison wants to give Liam his name. He adores him as though he were his own flesh and blood. Harrison is the only dad Liam has ever known.
"There is just one detail Harrison will have to take care of - marrying Calista. She says it is fine if Harrison adopts her boy, but she wants to walk down the aisle first."
