The Russian former world number one was this week refused a wildcard for the French Open following her 15-month ban for taking meldonium.
"Because of my improved ranking after the first three tournaments of my return, I will also be playing the qualifying of Wimbledon in Roehampton, and will not be requesting a wildcard into the main draw," said Sharapova on her website.
The 30-year-old was controversially handed a wildcard for next month's WTA grasscourt event in Birmingham, a key warm-up for Wimbledon with eight of the world's top 10 set to take part, including world number one Angelique Kerber.
Sharapova returned from her doping ban on April 26 but relied on wildcards to get into tournaments because her world ranking points expired while she was banned. The five-time Grand Slam winner had plummeted to 211.

She was initially banned for two years for using meldonium, with the penalty later reduced by the Court of Arbitration for Sport (CAS), which ruled she was not an intentional doper.
Sharapova this week responded to her French Open wildcard snub with a defiant Twitter message, saying: "If this is what it takes to rise up again, then I am in it all the way, everyday."
The Russian also allayed fears about a thigh injury that saw her retire from this week's Rome Masters.
